A. Improving the Current Workflow To improve the current workflow in the plant Shuzworld needs change the facility layout so that production is more efficient. In order to do this they need to balance the amount of time spent at each workstation so that each employee is maximizing their time. According to the information provided 48 units of work boots are required for each 8-hour shift. Each shift totals 480 minutes divided by 48 units is 10 minutes‚ which is the maximum amount of time each task

A. 1. I recommend that the Rugged Boot assembly line be rearranged to provide a more efficient process. Based on the diagram provided by Catherine Pang showing the layout of the production line‚ the current line uses eight stations. I determined the efficiency by using the following formula: Efficiency = _____________Σ Task times___________________ (actual number of work stations) x (largest cycle time) The total task time for the work boot assembly is 46 minutes

1. F. James McDonald the former president of the US automobile workers federation suggested an average reduction of 4% in the price of the car. The automobile market was weak‚ which resulted in unemployment. Lower price would lead to greater sales and stimulate employment. McDonald believed that a 4% reduction in price would increase sales by 16%.David black‚ representing the management of the automobile manufacturers disagreed with McDonald’s estimation. Black cited studies which indicated price

Decision Analysis Task 1- Tara Johnson A. In order to improve the current workflow in the plant‚ I recommend using the work stations layout tool whether through the Excel or POM program. This will help to show a clearer picture of the work flow that is present at Shuzworld‚ with allotting equal times in each work station. This will enable the company to find the shortest time to be used in each station for optimal performance and production of all shoes. Decision Analysis has been established to
