En tant que Directeur de la chaîne d’approvisionnement, j’ai été mandaté pour assurer le succès logistique du nouveau modèle d’affaires.
Notre créneau de cartouches est en pleine évolution et la décision de déplacer nos opérations de fabrication en Asie est une opportunité intéressante. Cependant, il faut considérer quelques enjeux auxquels nous devrons faire face. En effet, le problème majeur est que la logistique actuelle ne permet pas de répondre adéquatement au changement d’orientation de l’entreprise. De plus, plusieurs problèmes sous-jacents sont à prévoir dont voici les principaux: * gestion des stocks plus complexe * activités de distribution inadaptées * marché en croissance et nouveaux compétiteurs
Ma recommandation est donc de se doter d’une équipe projet qui permettra de mettre en œuvre un plan de logistique et transport répondant aux objectifs communs de croissance, de rentabilité et de distribution efficace.
Il faut mettre les efforts dans le réseau de distribution car il deviendra le cœur des activités de Teckn-O-Laser.

Enjeu
Le problème à court terme est qu’une transition vers un nouveau modèle d’affaires est annoncée par la direction mais aucun plan de réalisation n’a été complété. Une décision doit être prise dans les plus brefs délais concernant le choix du fournisseur de logistique afin de mettre en place un plan de distribution et de transport impliquant dorénavant des opérations outre-mer.

Perspective stratégique
La nouvelle mission de l’entreprise s’inspire directement de la vision de M. Léveillé. Le marché des cartouches est en pleine évolution et la concurrence asiatique arrive à grands pas. On doit se repositionner maintenant en vue de garder et augmenter nos parts de marché. Nos clients sont satisfaits et notre réputation est enviable tant pour notre capacité de gestion, d’innovation et son sens du devoir sociétal. Nos sommes l’entreprise la plus importante dans le marché des cartouches au Canada. On doit tirer profits de notre expérience afin d’assurer le succès de la transition souhaitée.

Analyse qualitative
Gestion des stocks - Délais d’approvisionnement plus longs
Les cartouches n’étant plus fabriquées près du lieu de distribution, le délai d’approvisionnement passera de 1,5 semaine à 3,5 mois. S’il y a un changement d’une commande, nous serons dans l’incapacité de compléter les commandes à temps. L’obligation de faire une livraison supplémentaire en provenance d’Asie pour répondre à une commande urgente risque de nous coûter très cher.
De plus, il faudra commander plusieurs mois à l’avance, ce qui engendre une logistique plus complexe dû à une chaîne d’approvisionnement plus étendue. On devra non seulement prévoir les ventes par produit mais aussi d’affiner nos prévisions. Une mauvaise planification créera des mix de produits erronés entraînant des ruptures de stocks et des produits invendus (désuétude).

Gestion des stocks - Stock de sécurité et transit
Les centres de distribution devront prévoir des espaces d’entreposage supplémentaires et ce, pour chaque produit afin d’éviter toute rupture de stocks. Nonobstant le coût de ces cartouches en entrepôts et en transit, les coûts d’assurance, de transport, de désuétude ou de bris représentent des sommes importantes qui seront immobilisées.
Un autre impact est la traçabilité de tous ces produits répartis à plusieurs endroits dans la chaîne. En conséquence, il y aura un impact financier dû à un investissement dans un système de gestion d’inventaire plus précis.

Activités de distribution - Modification des activités d’emballage, de douanes, de transport et d’opérations d’achat.
Les cartouches en provenance d’outre-mer devront être livrées en conteneurs, déchargées, comptées et réemballées selon le carnet de commandes. Des employés supplémentaires seront embauchés et des entrepôts loués pour exécuter ces tâches. Il en résultera un coût total d’acquisition plus élevé qui grugera une partie des profits. Le temps requis de ces manipulations doit aussi être pris en compte dans l’analyse de la chaîne d’approvisionnement pour éviter les retards dans les commandes aux centres de distribution.

Activités de distribution - Exécution d’un plan de transfert entre les centres de distribution
Dans les 3 prochaines années, la majorité des volumes sera destinée aux marchés américains. Le plan de distribution devra prévoir les livraisons directement à Memphis pour minimiser les coûts de transport et de douanes. De plus, le réusinage ne sera plus centralisé à Ste-Julie. Un plan de transfert doit être planifié selon le type de produit, signifiant un remaniement de la chaîne logistique et des activités dans chacun des centres de distribution. En conséquence, les employés seront confrontés à des modifications dans leurs tâches et il y aura forcément une résistance aux changements.

Évolution du marché - Croissance anticipée
Avec une croissance anticipée passant de 27K à 426K cartouches, les centres de distribution doivent être en mesure de répondre à la demande pour éviter des ruptures de stocks. Le plan de distribution actuel n’est pas adapté à cette augmentation de volumes. Sans une logistique à toute épreuve, le centre de distribution souffrira de ruptures de stocks qui créeront l’insatisfaction des clients.

Évolution du marché - Nouvelle concurrence
Teckn-O-Laser occupe une part de marché importante au Canada et jouit d’une réputation enviable. Par contre, l’arrivée de nouveaux produits provenant de pays étrangers risque de modifier notre stratégie de vente. Les nouveaux fournisseurs seront féroces pour attaquer le marché et attireront notre clientèle avec des prix agressifs. Nous n’aurons pas le choix de baisser nos prix de vente et cela grugera une partie de nos profits au risque de perdre des parts de marché importantes.

Analyse quantitative
Comme la majorité des entreprises, la rentabilité un des objectifs énoncés par M. Léveillé. Il serait opportun d’exprimer les économies que peut procurer une chaîne d’approvisionnement. Par conséquent, voici une mesure démontrant l’importance de s’attaquer aux problèmes d’approvisionnement :

Marge bénéficiaire = 3,8%
Économie reliée à une meilleure gestion de la logistique = 150 000$

* Contribution financière potentielle pourrait s’établir à :
150 000$ / 3,8% = 3 947 000$ C'est-à-dire qu’une économie liée à une saine gestion est équivalente à une augmentation des ventes de près de 4M$, l’équivalent de +/- 40 000 cartouches vendues.

Alternatives de solutions
Certaines solutions sont envisageables pour réduire au minimum les impacts d’un changement de modèle d’affaires sur l’entreprise et pour assure

Lasers

...Information Search: LASER (Light Amplification by the Stimulated Emission of Radiation) In 1917 a process called Stimulated Emission, this is what makes lasers possible and was thought of by Albert Einstein. Although this was thought of so early, it took another 30 years before other physicists made practical usage of this principle. Once completed, scientists were amazed at the breakthrough, however it didn’t, at the time, have any real use. Lasers is a source of light used in our everyday lives. They are very focused and accurate sources of light, thus we find them almost anywhere and help us in many different ways. They are incredibly useful in the Medical Field. They are often used in Laser Eye Surgery and Laser Ulcer Removal. They do so, because the laser beam is so intense, it burns through a tiny amount of tissue within the eye. The laser can also be used as a scalpel, which can make a small incision to reach the stomach ulcer. Lasers are also used in Compact Disk Players, CDs/DVDs/Blu Ray, Super Market Scanners, Laser Shows, Fiber Optic Cables, Cutting, Measuring Distance and much more. Clearly lasers have a major impact in our lives as advancing human beings. Atoms can get “excited” when they take in light, heat and/or electricity. Usually though atoms will remain in a “ground state” which is more stable, and will return to this state within nanoseconds. However to return to this state, the atoms must relieve themselves of the current...

...About LASIK About LASIK surgery: LASIK is laser vision-correction in the blink of an eye . The ultimate solution to replacing contact lenses and spectacles. What is LASIK? LASIK stands for ‘Laser In-Situ Keratomileusis’ which means ‘ to shape the cornea within its layers with the use of the Excimer laser’. Hi-tech solution combining advanced computer technology with laser precision: LASIK is a skilled procedure that combines the state-of-the-art computer technology with advanced laser precision. While the earlier laser procedure viz PRK treated the surface of the cornea, LASIK treats the inner tissue of the cornea and restructures it in a manner which grains down myopia (minus power) and hypermetropia (plus power). LASIK Knowledge Centre: LASIK procedure -step-by-step: * First, the eye surgeon uses an instrument known as a microkeratome to make a thin flap of the outer layer of the cornea. * Then he folds back the flap, which remains attached on one side. * Next, he uses the cool laser light from the Excimer laser to ’ablate'‘ i.e. remove the pre-determined amount of tissue to reshape the cornea with great accuracy and corrects the individual's refractive error. * The cornea is made flatter to treat near-sightedness, and steeper to treat far-sightedness and/or more spherical to correct astigmatism. * Finally, after the laser is administered, he  lays back the corneal flap in its original position, where it bonds itself instantly. * Due to...

The whole twenty minute drive home all he can think about is how excited he is to take his family on a weekend trip to the beach. As he pulls into his driveway, he notices that the front light isn’t on like usual, but the fact is quickly lost in his mind as a thousand other thoughts are clamoring for his attention. Just as he steps through the threshold of the door, his phone goes off. It’s his wife. Something’s come up, their daughter isn’t feeling well. She tells Nick that they are at the local hospital and is about to tell him to pick something important up at the pharmacy when his phone dies. Panic sets in. The first thought that leaps into his head is what happened to his daughter. The second is what is he supposed to get to help her. After a couple minutes of searching around his house for a charger, Nick is finally able to call his wife back and discover that he was supposed to pick up the allergy medicine his daughter needs. While this situation may seem a bit more dramatic than a normal situation, dead cellphone batteries, and any battery for that matter, are becoming a familiar headache in a wireless world. But what if this headache had a cure? Imagine that instead of Nick’s phone dying once he got home, it started instantly charging once he entered his house. No cord or cable needed, just wireless...

This term refers to the necessary equipment or goods that will ensure the safety of the individuals installing the wires and the individuals using them later for maintenance and other purposes. This equipment includes helmets, protective clothing, goggles, and other equipment or garment or that is designed for the sake of protecting the workers from injury. • Safe Work Habits The very first step that needs to be taken is to ensure that the optic fiber and copper cables that are about to be installed should comply with all the three requirements that includes the federal regulations, the international standards and the companies requirements. It is also important to wear your PPE and have the proper tools needed for the job. These are the safety rules that need to be followed with fiber optic and copper cable installation: 1. Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2. Wear disposable aprons to minimize fiber particles on your clothing. Fiber particles on your clothing can later get into food, drinks, and/or be ingested by other means. 3. Always wear safety glasses with side shields and protective gloves. Treat fiber optic splinters the same as you would glass splinters. 4. Never look directly into the end of fiber cables until you are positive that there is no light source at the other end.

...would you use fiber instead of UTP copper? Fiber should be used instead of copper when the application requires an application speed to deliver a signal over a distance greater than 100 meters and when better security and resistance to EMI are critical operating factors. 3. In most Short-distance applications of 10-550 meters using optical fiber, multimode fiber is the preferred choice over single-mode fiber. This is because single-mode- based systems are more expensive than multimode cable, what factors lead to single-mode systems being more expensive? A total optical system includes the cable, connectors, connectivity apparatus, and electronics. Since single-mode fiber has a much smaller core size, the manufacturing tolerances of lasers, connectors, and connectivity apparatus is much tighter than multimode parts. As a result, these parts are more expensive and lead to the overall single mode system being more expensive. 4. What is the primary performance factor affecting multimode fiber transmission capability and how can you minimize this? The main performance factor affecting multimode transmission is modal dispersion. Modal dispersion can be minimized by specifying a 50 micron multimode fiber instead of a 62.5 micron fiber because 50 micron fiber transmits fewer modes and thereby has lower inherent modal dispersion. Once 50 micron fiber is specified, modal dispersion can be...

Hologram Projector: a Product Innovation

...Definition Hologram Projector with an in-house computer system capable of feeding the projector with fully uncompressed video files. It consist of two technologies namely, the holography and the projector. Holography is a method which allows three-dimensional images to be made. It includes the use of a laser, interference, diffraction, light intensity recording, and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object are still present, therefore making it three-dimensional. The projector that will be used in this project is a overhead projector. An overhead projector is a variation of the common slide projector that is used to display images to a group of people. II. Project Description Hologram Projector is a projector wherein it can reflect the full dimension of an image. It consists of a laser, interference, and diffraction, light intensity recording and suitable illumination of the recording. Hologram Projector is AC operated.

...Introduction Increasing necessity of e-mail, Internet resources etc, offers serious security concerns. Biometrics is replacing passwords. Biometrics can be defined as recognizing and identifying a person based on physiological or behavioural characteristics. Unlike the skin, through which near-infrared light passes, deoxygenated haemoglobin in the blood flowing through the veins absorbs near-infrared rays, causing it to be visible as black regions to the scanner. Arteries and capillaries, whose blood contains oxygenated haemoglobin, which does not absorb near-infrared light, are invisible to the sensor, hence we chosen “VEINS”. Fujitsu research is the one main company which has come up with first basis of “PALM VEIN TECHNOLOGY". Reflection photography: There are two types of vein photography- 1. Reflection Reflection is more useful technique at low ambient temperatures as blood flow decreases at cool temperatures. 2. Transmission At cool temperatures transmission method provides low contrast images. Advantages: 1. Very economical. 2. Highest factor of security. 3. One time registry and usage throughout life. 4. More advantageous than other biometric techniques. Applications: 1. Managements in healthcare. 2. Operator authentication. 3. Owner authentication. 4. Attendance authentication.

...Final examination Theory 1. Explain the dispersion of light by a transparent dielectric material. The phenomen of dispersion is connected to the fact that the refractive index is dependent on the wavelength. Due to dispersion, the light waves from a complex radiation are bent by different angles as they enter a dispersive medium and they may be visualized separately. The index of refraction of a transparent dielectric medium is defined as the ratio of the speed of an electromagnetic wave in empty space to its speed in the medium. . It is a measure of the slowing factor for light traveling in that medium The refractive index can be expressed as a function of the electric and magnetic properties of the medium . For most of the materials that are transparent to visible light and . Hence the magnetic properties have a small effect on the light propagation. When an electromagnetic wave is incident on a medium, it electrically polarizes the molecules. This changes the value of which in its turn, determines the index of refraction. The process is wavelength dependent: different wavelengths will induce different polarizations of the molecules and, as a result, and will be different. So, the index of refraction changes with wavelength: The phenomenon described above is known as the dispersion of light. Equation is the dispersion relation. For most of the materials, decreases with the wavelength (see figure1). This phenomenon is known as normal dispersion...

What if I told you about a new in-prototype-development-stages technology called “Femto-Photography” that allows you to capture light at a half of a trillionth of a second [1]. Summary of Key Findings With Femto-Photography it is possible to “see around objects and walls” [1]. Normally when you fire a laser pulse at a wall, nothing crazy happens. But, with Femto-Photography, you’d be able to see that laser pulse hit the wall, propagate, bounce off of any objects within that room, hit said wall from a different point, and detect that there was/were objects or people in the room [1]. In 20 years’ time, this technology could be insanely useful and effective in traffic accident scenarios, emergency rescue situations with firefighters, and the list goes on and on. With Femto-Photography, it is also possible to “see through objects” [1]. In 20 years’ time there could be an enormous amount of possible applications of this use, between checking the ripeness of a fruit without touching it, x-raying a person’s body without the use of radiation, and many other applications, the possibilities are virtually limitless [1].
