Problem 1: The Seiko Watch Company has developed its aggregate plan for quartz watches. Each employee can produce about 300 watches per month and earns an average of $1,800 per month. It costs $100 to hire a new employee and $200 to lay one off. Determine total employee related costs of the following aggregate plan if work force is varied to met production.
Problem 2: The assembly of aluminum storm windows requires the following tasks (see attachment). The company operates on 9-hour shift and allows one hour for coffee breaks, lunch, and cleanup of work stations. The daily demand for storm windows is 360 units.
a) Determine the cycle time.
b) Determine the minimum number of workstations.
c) Group the line for balance and determine the level of efficiency of this line.
Problem 3: Given the following (see attachment) layout of 6 different departments and the frequency of movements among them along with the distance between each department, determine if less material handling is achieved by switching departments D and F. Assume diagonal distances to be 2 units and horizontal/vertical distances between adjacent departments to be 1.
Problem 4: A detergent manufacturer uses a single facility for filling and packaging all its 4 major types of detergents. The inventory at the beginning of a particular week, the average demand, the production rate, and lot size are given below (in ounces)(see attachment). If run out time is used for scheduling this activity, how would the activity be scheduled during the first 4 weeks?© BrainMass Inc. brainmass.com October 25, 2018, 7:39 am ad1c9bdddf

Select a minimum of two industries
Need suggestions/ideas on following -
1. Select a minimum of two industries (or specific companies) and identify how reselling, selling via outlet, salvaging, reconditioning, refurbishing, and remanufacturing can help that company optimize its reverse logistics supply chain.
2. Explain the relationship between optimization of the reverse logistics channel and the overall supply channel.
