Note: Do not program the non-negativity constraint, as this is already assumed by the software. For additional support, please reference the POM-QM for Windows manual available from the ‘Help’ menu in the POM-QM Windows software.

Individual Project, part 1

A firm uses three machines in the manufacturing of three products:

  • Each unit of product 1 requires three hours on machine 1, two hours on machine 2 and one hour on machine 3.
  • Each unit of product 2 requires four hours on machine 1, one hour on machine 2 and three hours on machine 3.
  • Each unit of product 3 requires two hours on machine 1, two hours on machine 2 and two hours on machine 3.

The contribution margin of the three products is £30, £40 and £35 per unit, respectively. The following are available for scheduling:

  • 90 hours of machine 1 time
  • 54 hours of machine 2 time
  • 93 hours of machine 3 time

The linear programming formulation of this problem is as follows:

Maximise Z = 30X1 + 40X2 + 35X3

Subject to:

  • 3X1 + 4X2 + 2X3 ≤ 90
  • 2X1 + 1X2 + 2X3 ≤ 54
  • X1 + 3X2 + 2X3 ≤ 93

with X1, X2, X3 ≥ 0. To answer this question: answer each question and explain your reasoning or show your calculations.

1. What is the optimal production schedule for this firm? What is the profit contribution of each of these products?

2. What is the marginal value of an additional hour of time on machine 1? Over what range of time is this marginal value valid?

3. What is the opportunity cost associated with product 1? What interpretation should be given to this opportunity cost?

4. How many hours are used for machine 3 with the optimal solution?

5. How much can the contribution margin for product 2 change before the current optimal solution is no longer optimal?

Paper For Above instruction

The given assignment encompasses two interconnected projects utilizing the POM (Production and Operations Management) software: a linear programming (LP) problem and a project management problem modeled through PERT/CPM techniques. This comprehensive analysis aims to demonstrate proficiency in LP formulation, solution interpretation, and project scheduling using POM software tools. The first part involves developing and solving an LP model to optimize product mix and resource utilization in a manufacturing setting, while the second addresses project duration estimation, critical path identification, and probability analysis for project completion.

Part 1: Linear Programming for Manufacturing Optimization

The manufacturing firm produces three products—X1, X2, and X3—each requiring specific machine hours across three equipment units with respective contribution margins forming the objective function. The resource constraints reflect machine availability, ensuring production feasibility without exceeding available machine hours. The LP formulation is as follows:

Maximize Z = 30X1 + 40X2 + 35X3

subject to:

  • 3X1 + 4X2 + 2X3 ≤ 90
  • 2X1 + 1X2 + 2X3 ≤ 54
  • X1 + 3X2 + 2X3 ≤ 93

X1, X2, X3 ≥ 0.

By solving this LP in POM software, the optimal production quantities are obtained, enabling calculation of optimal profit contributions per product. The solution illustrates the production quantities that maximize profit while meeting resource constraints.

Part 2: Project Scheduling with PERT/CPM

The second part centers on a project scheduling problem where multiple activities with known mean durations and standard deviations are analyzed to estimate total project duration, identify critical activities, and assess completion probabilities. Using the POM-PERT/CPM module, the process includes:

  • Calculating the expected project completion time, which involves summing the mean durations along the critical path identified through the network diagram.
  • Identifying the critical path by analyzing activity slack and sequence dependencies, critical in project management for resource allocation and risk mitigation.
  • Assessing the probability that the project will conclude within a specific timeframe requires calculating the Z-score based on normal distribution assumptions of activity durations.
  • Finally, slack values for activities such as C and F reveal flexibility in their scheduling, guiding managers on where delays might be permissible without impacting overall project completion.

In executing these tasks, familiarity with POM's modules for linear programming and project management, combined with analytical interpretation of results, is essential. Such expertise aids operational decision-making, optimal resource allocation, and risk assessment essential in managerial contexts.
