Part A is processed on a MILLING machine; Part B is processed on a LATHE machine. Two parts (A and B) are then assembled on an ASSEMBLY machine. Standard times, scrap rates, efficiency, and availability of each machine and the assembly are given in the table below. Determine the number of milling (M), the lathe (L) and the assembly (A) machines needed to produce 100 good parts from this production system during and 8-hour (480 minutes) shift. (Note: Round up the number of parts processed on each station and then round up the number of machines needed).
Show your step-by-step process using the SPECIAL PURPOSE LINEAR PROGRAMMING: ASSIGNMENT METHOD to solve this problem. Four Engineers are to work on 4 projects of Dora Company. The problem is to decide which engineer should be assigned to which project. Each engineer charges different fees on each project, due to distances of the projects and the complexity of the work. The cost of assigning particular engineers to particular projects are as stated below. The objective is to find the lease cost of assignment. Engineer 1 to Projects A, B, C, D = $11k, $8k, $10k, $7k respectively.Engineer 2 to Projects A, B, C, D = $6k, $5k, $3k, $8k respectively.Engineer 3 to Projects A, B, C, D = $4k, $8k, $10k, $9k respectively.Engineer 4 to Projects A, B, C, D = $11k, $10k, $5k, $7k respectively.
A manufacturing system is used to produce a product.Each unit of product must be processed sequentially through workstations.V -----> W -----> X -----> Y The capacity of each workstation are as follows:Workstation V, 16 units per hour,Workstation W, 22 units per hour, Workstation X, 13 units per hour,Workstation Y, 18 units per hour. The raw material is always available in the front of workstation V. The manufacturing system has a cycle time of __________ minutes per unit. Use at least 4 decimals.You must show your calculation steps and brief explanation on your Excel spreadsheets.

A service process is described by the above flowchart. After going through workstation A, an order needs to be processed by one of the three lines, B1-C1-D1, B2-C2-D2, or B3-C3-D3 (in other words, they are substitutable). Finally, all orders need to go through workstation E. The capacities of the individual workstations are given as follows: Workstation A has a capacity of 2 orders/hour Workstation B1, B2, and B3 have the same capacity of 3 orders/hour Workstation C1, C2, and C3 have the same capacity of 3 orders/hour Workstation D1, D2, and D3 have the same capacity of 3 orders/hour Workstation E has a capacity of 4 orders/hour What is capacity of the service process in orders/hour? Note: Please do not include the unit of measure. For example, if your answer is 10 orders/hour, enter 10.
Assign the 4 departments in Table X to locations A, B, C, and D, which are separated by the distances shown in Table y, in such a way that transportation cost is minimized. Use this heuristic: assign departments with the greatest interdepartmental workflow first. (See attached table) Illustrate the configuration of the 4 departments in each of the 4 locations. Show the distances between departments and total interdepartmental workflows of department pairs.
EU Company manufactures two different types of life vests (A and B) that are manufactured and assembled on three different workstations (W, X, and Y) using a small-batch process (see Figure 1). Batch setup times are negligible. The flowchart denotes the path each product follows through the manufacturing process, and each product’s price, demand per week, and processing times per unit are indicated as well. Purchased parts and raw materials consumed during production are represented by inverted triangles. EU can make and sell up to the limit of its demand per week; no penalties are incurred for not being able to meet all the demand. Each workstation is staffed by a worker who is dedicated to work on that workstation alone and is paid $6 per hour for an entire week, regardless of how much the worker is used. Total labor costs per week are fixed. Variable overhead costs are $1,500/week. The plant operates one 8-hour shift per day, or 40 hours/week. Which of the three workstations, W,…
Green Vehicle Inc., manufactures electric cars and small delivery trucks. It has just opened a new factory where the C1 car and the T1 truck can both be manufactured. To make either vehicle, processing in the assembly shop and in the paint shop are required. It takes 1/25 of a day and 1/60 of a day to paint a truck of type T1 and a car of type C1 in the paint shop, respectively. It takes 1/45 of a day to assemble either type of vehicle in the assembly shop. A T1 truck and a C1 car yield profits of $300 and $220, respectively, per vehicle sold. The optimum solution is: Number of trucks to be produced per day = ? (round your response to two decimal places).

In an evaluation of labor assignment rules when workers are not perfectly interchangeable, Paul. M. Bobrowski and Paul Sungchil Park created a dynamic job shop with 9 work centers and 9 workers, both numbered 1–9.

Posh Nails Katie Posh runs an upscale nail salon. The service process includes five activities that are conducted in the sequence described below. (The time required for each activity is shown in parentheses): Activity 1: Welcome a guest. (1 minute)Activity 2: Clip and file nails. (3 minutes)Activity 3: Paint. (5 minutes)Activity 4: Dry. (10 minutes)Activity 5: Check out the customer. (4 minutes)Three servers (S1, S2, and S3) offer the services in a worker-paced line. The assignment of tasks to servers is the following: S1 does Activity 1. S2 does Activities 2 and 3. S3 does Activities 4 and 5. The drying process does not require server 3’s constant attention; she/he needs to only escort the customer to the salon’s drying chair (equipped with fans for drying). The time to do this is negligible. There exists only one drying chair in the salon. Assume a wage rate of $12 per hour. What are the direct labor costs for one customer (in dollars)?
