...Decision Analysis 3/1/2014 Unknown A. Workflow In order to improve the workflow in the plant, Shuzworld will have to improve the layout of their facility in order to create their product in a cost efficient and productive manner. This will enable Shuzworld to increase productivity, while ensuring the quality that consumers have grown to be accustomed to. Shuzworld will be able to accomplish this by equalizing the task times at the company’s work stations in order to ensure that employee time is maximized to its full potential. This can be accomplished by organizing employees into work cells that focus primarily on the product they are working on. By focusing on the product within the work cell, the company will be able to make better use of the production floor, as well as reduce the amount of direct labor required while increasing the sense of participation by employees. This will translate into higher rates of productivity on the assembly lines. One way to improve the work area for the employees is to create work cells that enable employees to communicate with each other in a simpler fashion, as well as have employees cross trained so that they can intervene and assist when necessary. Instead of having a traditional assembly line, the assembly line should be made into a U shape. The U shaped assembly line will reduce the amount of employee movement, and make it easier for employees to communicate amongst themselves during the construction process (MyOMLabs, 2012)...

...decision Analysis - Jgt Task 1 Decision Analysis Decision Analysis Task 1 A Answer to Question A and A1. The answer relates to Shuzworld’s Rugged Wear Work Boot Assembly Line issue. The Shanghai facility of the company produces steel tipped work boot. The scope of this task is to analyze if the company has properly organized workflow associated with the production of this item. Presented below, Table 1 and Figure 1 demonstrate arrangement of tasks of the production line. Table 1 Task Description of Work boot |Tasks |Completion (Minutes) |Predecessors | |A |10 |N/A | |B |6 |A | |C |3 |A | |D |8 |B, C | |E |3 |D | |F |4 |D | |G |3 |E, F | |H |9 |G | Note: Consumed time for time is 46 minutes. (Courtesy: Shuzworld) Figure 1. Workflow Diagram Both Table 1 and Figure 1 provide information of tasks associated with the production of the work boot. The workflow diagram in Figure 1 shows that some tasks are parallel, and others are sequential. In other words, some tasks can start together, and others cannot start unless the previous task is completed. Table 1 shows that the task A takes 10 minutes to complete; it is the longest task in this schedule. The production line consumes 46 minutes to complete all tasks. It produces 6 boots in an hour and maintains 40-hour per week work schedule. The plant’s operation director, Alistair Wu wants to find out how to optimize tasks from A to H, described in the Table 1 and Figure 1. The concept implies that the tasks within the assembly...

...Technical Supplement 3 Learning Curves LEARNING OBJECTIVES After studying this technical supplement, you should be able to: 1. Explain the learning curve concept 2. Identify different uses of learning curves in operations management 3. Calculate the estimated time required to do a task for a given learning curve LEARNING CURVES AND OPERATIONS MANAGEMENT As people gain experience in doing a task, they usually can do the task more quickly. For example, consider the time it might take someone to wash a car for the first time. Then imagine how that person might be able to wash his car in less time as through repetitions he learns to sequence the tasks more efficiently or perhaps as he uses better tools to do the tasks. The same learning effect occurs in many different operational settings. The learning curve is an analytical tool that can be used to estimate the rate at which cumulative experience allows workers to do tasks faster and with less cost. Operations managers use learning curves to estimate how much the repetitions of a task will enable them to reduce the amount of resources required to accomplish the ask. A learning curve is defined by an equation that contains the rate of improvement (i.e., reduction in costs or reduction in time taken) in performing a task as a function of the cumulative repetitions of the task. As early as 1925, managers began developing learning curve concepts. The commander at Wright-Patterson Air Force Base in Dayton...

...* Change the task type settings to control how resources affect task assignments * Apply a preset resource contour to change work value distribution * Working with task information forms When planning a project schedule, adjustments are often needed to reflect necessary changes in project scope, assignments, etc. In MS Project, when an assignment is changed, the schedule is recalculated to display the changes. You can work with the scheduling method and the task type settings when making changes to the initial resource assignment. In the previous lesson, the initial resource assignments were made for our project. But we need to learn how to make adjustments to how those resources are used. It is important that you read every part of this lab carefully, if not twice. Working with Effort-Driven Scheduling How a task reacts to the addition and removal of resources is defined by the scheduling method and the task type settings. In MS Project, the default scheduling method is effort-driven scheduling. Effort-driven scheduling extends or shortens the duration of a task to accommodate changes to resources but doesn't change the total work for the task. Work is the amount of effort, or number of hours, resources put into a task. The total work for a task is determined by the duration estimate for the task and the initial resource assignment using the following formula: Work = Duration * Units For example, say you give a task the duration of...

...MEMORANDUM To: Shuzworld From: Robert Hixon Director of Operations When we face challenges in life that are far beyond our own power, it's an opportunity to build on our faith, inner strength, and courage. I've learned that how we face challenges plays a big role in the outcome. Stay ambitious & determined and you can Never fail. Re: Operations Recommendations Date: November, 06, 2012 A) Work Flow The current workflow needs to address how to best organize the assembly line so that it is most efficient, and what metrics can be provided in determining the correct number of workstations. My recommendation to improve work flow is to utilize assembling and balancing strategies in Shuzworld’s Shanghai Production Facility (SSPF). Due to the circumstances surrounding this issue, I have chosen this decision analysis tool because the goal of using a layout strategy is “to develop an effective and efficient layout that will meet the firm’s competitive requirements” (JGT2 power point presentation). Proper job layouts must support a business's competitive priorities: process, flexibility, customer contact, and quality of work life. Although there are a variety of layouts to choose from, I recommend using the Product Oriented Layout in order to maximize the long run efficiency of operations by achieving the following: Higher utilization of space, equipment and people, improved flow of materials, information and people, improved employee morale...
