Problem 1: Shipping Alternative Decision at Strateline Manufacturing
A manager at Strateline Manufacturing is choosing between two shipping options: two-day freight and five-day freight. The five-day freight costs $135 less than the two-day option. The primary consideration is holding costs, which are $10 per unit annually. A total of 2,000 items are to be shipped. Which shipping alternative would you recommend and why?
The decision involves evaluating the total costs, including shipping and holding costs. The key is to compare the costs under both options by calculating the total costs associated with each shipping method considering the inventory holding costs for the period each shipment would keep inventory in stock. The economic order quantity (EOQ) principles apply here, where shorter lead times could increase costs due to higher shipping charges, but might decrease holding costs due to quicker inventory turnover.
Calculations should include:
- Total shipping costs = shipping rate per unit * number of units
- Holding costs = average inventory level * holding cost rate
The alternative with the lowest total cost, accounting for both shipping costs and holding costs, should be recommended.
Problem 2: Shipping Decision between Two Shippers
A manager must decide between two shippers, A and B. Both offer a two-day rate: A costs $500, B costs $525. Shipper A also offers a three-day rate of $460 and a nine-day rate of $400, whereas Shipper B offers rates of $450 for four days and $410 for seven days. The annual holding costs are 35% of the unit price. The shipment involves 300 boxes, each costing $140. Which shipping option do you recommend, and what is your reasoning?
In this problem, the goal is to compare total costs, which include shipping costs and inventory holding costs. The calculation involves these steps:
- Calculate the shipping cost for each alternative.
- Determine the average inventory held, usually estimated as half the order quantity or shipment duration times the daily demand (if applicable).
- Compute total holding costs by multiplying average inventory by holding rate and unit cost.
- Sum shipping and holding costs for each option to find the total cost.
The optimal choice minimizes the combined cost. The decision should be based on which shipping method offers the lowest total expenditure considering both transportation expenses and inventory costs over the period.
Problem 3: Assigning Workers to Jobs Using the Assignment Method
Using the assignment method, determine the best way to assign workers to jobs based on the following cost data. Calculate the total cost for the assignment plan.
Cost table (example):
| Worker | Job A | Job B | Job C |
|---|---|---|---|
| Worker 1 | $ | $ | $ |
| Worker 2 | $ | $ | $ |
| Worker 3 | $ | $ | $ |
Fill in the missing costs and apply the Hungarian Algorithm (or other assignment technique) to find the optimal assignment and compute the total minimized cost.
Problem 4: Truck Routing to Minimize Delivery Costs
Assign trucks to delivery routes provided in the data to minimize total transportation costs. For each truck, determine the assigned route, and then sum the individual costs to find the total cost.
Sample data:
| Route | Truck 1 | Truck 2 | Truck 3 | Truck 4 | Truck 5 |
|---|---|---|---|---|---|
| Route A | $ | $ | $ | $ | $ |
| Route B | $ | $ | $ | $ | $ |
| Route C | $ | $ | $ | $ | $ |
| Route D | $ | $ | $ | $ | $ |
| Route E | $ | $ | $ | $ | $ |
Determine the route assignment that minimizes total costs and calculate that total.
Problem 5: Job Sequencing and Scheduling Analysis
Given four jobs awaiting processing at a work center with known processing times and due dates, sequence the jobs using four methods: (1) FCFS, (2) SPT, (3) EDD, and (4) CR. List the jobs in order for each method with no spaces, e.g., ABCD.
For each method, compute these performance metrics:
- (1) Average flow time (the average time jobs spend in the system)
- (2) Average tardiness (the average lateness beyond due date)
- (3) Average number of jobs at the work center
Compare the methods and identify which scheduling rule is superior based on these metrics.
Problem 6: Processing at a Machine Shop
Jobs arriving at a machine shop must go through multiple operations within certain times. Using the provided data (processing times, due dates, number of remaining operations), determine the sequence of jobs at the first work center using FCFS and S/O rules.
Compute effectiveness measures for each rule:
- Average flow time
- Average number of jobs at the work center
Analyze which scheduling rule yields better performance metrics.
