Study Notes
PMGT3623 Scheduling - Week 10
- Topic: Complex Task Allocation Approach
- Lecturer: Dr Shahadat Uddin
- Topics Covered: Complex Task Allocation, Linear Programming (with Excel Solver demonstrations), Artificial Intelligence (AI) in Scheduling
- Previous Week's Learning: Simple task allocation approaches were categorized into Resource-centric, Task-centric, and Methodology-centric approaches. Exercises were completed on these approaches. Advanced allocation approaches will be covered this week.
Linear Programming
- Definition: A mathematical technique for optimization, where a linear objective function is maximized or minimized subject to a set of linear constraints.
- Scheduling Applications: Applied to optimize resource allocation, task scheduling, and project timelines to achieve specific goals (e.g., minimizing costs or maximizing resource utilization).
- Simplified Approach: The material will be presented as simply as possible, despite its mathematical nature.
- Alternative Name: Also known as Linear Optimization.
- Implementation Methods: Can be implemented using Excel and programming languages.
Linear Programming (cont.) - Key Components
- Objective Function: A linear equation representing the goal of optimization. In scheduling, it could aim to optimize project cost or duration.
- Decision Variables: Variables representing decisions to be made (start times of tasks, resource allocation, or the amount of time allocated to each task).
- Constraints: Linear equations representing limitations or requirements of the problem (resource availability, task dependencies, and deadlines).
- Feasible Region: The set of all possible solutions that satisfy the constraints. The optimal solution lies within this region.
Linear Programming (cont.) - Example Application in Scheduling
- Project: Development of a Software Application
- Tasks: Requirements Gathering (2 days), UI/UX Design (5 days), Front-End Dev (10 days), Back-End Dev (10 days), Integration Testing (5 days)
- Task Dependencies: UI/UX Design depends on Requirements Gathering, Front/Back-End Dev depends on UI/UX Design, Integration Testing depends on Front/Back-End Dev. Specifically:
- UI/UX Design (x2) starts after Requirements Gathering (x1): x2 ≥ x1 + 2
- Front-End Development (x3) starts after UI/UX Design (x2): x3 ≥ x2 + 5
- Back-End Development (x4) starts after UI/UX Design (x2): x4 ≥ x2 + 5
- Integration Testing (x5) starts after both Front-End (x3) and Back-End Development (x4): x5 ≥ x3 + 10, x5 ≥ x4 + 10
- Objective: Minimize total project duration (Z = x5 + 5)
Linear Programming - Formulated Program
- Minimise Z = x5 + 5
- Subject to:
- X2 - X1 >= 2
- X3 - X2 >= 5
- X4 - X2 >= 5
- X5 - X3 >= 10
- X5 - X4 >= 10
- X1, X2, X3, X4, X5 ≥ 0
Linear Programming - Advantages and Limitations
- Advantages: Optimal solution, flexibility, resource allocation effectiveness, applicable to various scenarios, handling large-scale problems, clarity of structure, decision support.
- Limitations: Often assumes that relationships are linear; certainty assumption concerning coefficients isn't always realistic in real world applications; variables can often be continuous when integers are needed.
Linear Programming and Crashing (Week 6)
- Problem Statement: Minimize total project cost while meeting a project deadline of 18 days.
- Decision Variables: Crashed days for each task
- Target Variable: Project cost.
Artificial Intelligence (AI) in Scheduling (Week 10)
- Generative AI (Large Language Model): A potential next-generation approach to scheduling is highlighted.
