A shoe assembly plant buys leather tops and soles from its suppliers. The leathertops have no color on them when bought. The assembly plant first dies the leather with colors likeblack, beige, brown and cream. Then it sews the colored leather tops to the soles. Finally leather topsare polished with an agent that depends on the color of the shoe. Basically there are three operationsin the shoe plant: Coloring, Sewing and Polishing. The activity times and set up times for theseoperations are given in minutes as follows:Operation Coloring Sewing PolishingActivity time 0.25 0.20 0.15Set up time 30 20 45 Soles and the leather top-sole assemblies are processed in batches in all operations. The batch sizesare kept the same at all operations. Before a batch goes through an operation, the shoe plant mustset up the machines for that operation.a) How many leather tops can be colored in an hour with a batch size of 40?b) Explain why sewing cannot be the…
A company is setting up an assembly line to produce 90 units per hour. The table below identifies the work elements, times, and immediate predecessors. Work Element Time (Sec.) Immediate Predecessor(s) A 25 - B 18 A C 20 A D 5 B, C E 12 C F 8 E G 16 D, F H 12 G Use one of the heuristic decision rules described in Table below to balance the assembly line so that it will produce 90 units per hour. Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker. It can be tried…
