Quantitative Modules:
I Love Coffee (ILC) illustrate a waiting-line system. The Queuing theory is a very important aspect of operations at ILC, and plays as vital tool to ILC’s operations manager. I Love Coffee drive through, implements a queuing system with its customers, having customers wait in line for the product.
Characteristics of the waiting –line system at the I Love Coffee drive through. First using the arrivals or input in the systems of all the customers of (ILC) this will help build a database to better understand aspects of the ILC’s customers, such as the size or number of customers in given period of time, and certain patterns that emerge to help demonstrate a better understanding an example would be statistical distribution. With respect to the size of the population at I Love Coffee, it has an unlimited population. Patterns of customer arrivals at (ILC) show a rise in arrivals between 07:00AM – 11:00AM and 6:00PM – 12:00AM with intervals varying from 3:00 to 5:00 minutes per arrival or customer. Moreover, with regards to the waiting line characteristics ILC has a limited queuing system that can take 6 vehicles at one certain time period, more over the drive through also acts as the service facility, supplying the coffee through designated collection windows.
Additionally, to have a better quantitative understanding of the arrival rate with regards to the queuing theory, a discrete Poisson distribution can be established by the following: x: 3 P(x)= Probability of 3 arrivals = 14.037% y: 5 e:2.71828 Furthermore, another waiting-line characteristic with respect of the queuing discipline. ILC uses a first-in, first-out (FIFO) rule, with a basic queuing system design that involves a single-phase queuing system (M/M/1). This system operates with a Poisson arrival rate pattern, with an exponential service time pattern.
I Love Coffee drive through, is able to service hot caffeinated beverages at an average rate of 30 cups per hour, according to a negative exponential distribution. Customers wanting hot caffeinated beverages arrive at the drive through on an average of 18 cars an hour, moreover following a Poisson distribution, they are served on a FIFO from a very large population of possible customers, thus to have a better understanding of ILC’s queuing system:
Y: 18 cars arriving per hour
U: 30 cups served per hour
Ls= y/u-y = 18/12 = 1.5 cars in the system on average
Ws= 1/u-y = 1/30-18 = 1/12
= 5 min average waiting time in the system
Lq= y2/u(u – y) = 18^2/30(30-18) = 324/360 = 0.9 cars waiting in line on average.
Wq= y/u(u – y) = 18/30(30 – 18) = 18/360 = 0.05*60 = 3 min average waiting time per car.
P= y/u = 18/30 = 0.6*100 = 60% of the time the drive through is busy.
P0= 1 – y/u = 1 – 18/30 = 0.40 probability there are 0 cars in the system.

Case Study of “Does America Really Need Manufacturing”.

...Case Study of “Does America really need manufacturing”. Sriharsha Vennelaganti-Fs0792 1. Summary: In the case study we can see that the authors talk about the importance of innovation when it comes to the long-term success of every product company. By reading the article one gets an understanding that the authors are asking executives of any product company should not view manufacturing as a cost center and by shifting their manufacturing units offshore they are hindering a company’s capacity to innovate. In the end the authors give us different methods that a company can use to better improve their product line without shifting their manufacturing bases offshore and a way the government can help by providing policy incentives for the companies so that they can open their manufacturing units in United States. 2. Key Points: When we read this case study the one major point it talks about is the importance of manufacturing for United States. The article talks about the importance of product and process innovation, the role R&D plays in manufacturing. In the case study we can see that the authors talk about modularity and the maturity of manufacturing process. Modularized products lead to flexibility when it comes to the needs of end users and marketing. When it comes to manufacturing process the article talks about manufacturing levers such as sourcing and process innovation. From reading the article we can see that the authors provide an inherent understanding of the relationship...
