a)
Interpretation:The planned order release for the valve casing is to be determined.
Concept Introduction:
The operational feasibility can be defined as the measurement of the problem solving capacity of the proposed system and it also checks that in which manner this proposed system is satisfying the requirements which are identified in the requirement analysis phase during the system development.
b)
Interpretation: The gross requirements schedule for the valves obtained for the lot sizing is to be calculated.

EBK PRODUCTION AND OPERATIONS ANALYSIS
- Phil's first step was to prepare a master schedule for one of the engine types produced by Brunswick: the Model 1000 engine. This schedule indicates the number of units of the Model 1000 engine to be assembled each week during the last 12 weeks and is shown on the next page. Next, Phil decided to simplify his requirements planning example by considering only two of the many components that are needed to complete the assembly of the Model 1000 engine. These two components, the gear box and the input shaft, are shown in the product structure diagram below. Phil noted that the gear box is assembled by the Subassembly Department and subsequently is sent to the main engine assembly line. The input shaft is one of several component parts manufactured by Brunswick that are needed to produce a gear box subassembly. Thus, levels 0, 1, and 2 are included in the product structure diagram to indicate the three manufacturing stages that are involved in producing an engine: the Engine Assembly…arrow_forwardA initially assume that Phi wants to minimize his inventory requirements. Assume that each order will be only for what is required for a single period. Calculate the net requirements and planned order releases for the gear boxes and input shafts. Assume that lot sizing is done using a lot-for-lot (L4L).

As part of the development process, a manufacturing testrunwill be conducted, requiring an extra 500 subassembly C’s per week.What is the earliest week this extra production can be added while stillmaintaining the inventory requirements of all components?arrow_forwardCan you provide step by step for every requirement?arrow_forwardThe planned order releases (POR) for three components: A, B, and C, are giving below. Suppose that the yields for these components are respectively 88 percent, 90 percent, and 78 percent. Assuming lot-for-lot scheduling, how should these planned order releases be adjusted to account for the fact tha the yields are less than 100 percent? Be specific with calculations.

The tablerequires a top, four legs, 18 gallon of stain, 116 gallon of glue, 2 shortbraces between the legs and 2 long braces between the legs, anda brass cap that goes on the bottom of each leg. She has 100 gallons of glue in inventory, but none of the other components. Allitems except the brass caps, stain, and glue are ordered on a lotfor-lot basis. The caps are purchased in quantities of 1,000, stainand glue by the gallon. Lead time is 1 day for each item.
