Refactor Mode Vars By Introducing Task Alternatives And Mode Booleans

by ADMIN 70 views

Problem Statement

In the current implementation, we rely heavily on mode_vars to manage different modes and their associated tasks and resources. However, this approach has a significant drawback: it makes sequencing very cumbersome to implement. The complexity arises from the need to manage multiple modes, tasks, and resources, which can lead to a tangled web of dependencies and make it challenging to reason about the system's behavior.

Proposed Solution

To address this issue, we propose a refactor of the current implementation by introducing two new concepts: optional interval variables for each (task, resource) pair and mode boolean variables for each mode. This approach will not only simplify sequencing but also make it easier to implement other features, such as #296.

Introducing Optional Interval Variables

The first step in our proposed solution is to introduce optional interval variables for each (task, resource) pair. These variables will allow us to associate a specific interval with each task and resource, making it easier to manage their dependencies and sequencing.

Benefits of Interval Variables

  • Simplify sequencing: By introducing interval variables, we can decouple the sequencing logic from the mode variables, making it easier to manage complex dependencies.
  • Improve readability: Interval variables will provide a clear and concise way to express the relationships between tasks and resources, making the code more readable and maintainable.
  • Enhance flexibility: With interval variables, we can easily add or remove tasks and resources without affecting the overall sequencing logic.

Introducing Mode Boolean Variables

The second step in our proposed solution is to introduce mode boolean variables for each mode. These variables will allow us to toggle the presence of specific tasks and resources based on the selected mode.

Benefits of Mode Boolean Variables

  • Simplify mode management: By introducing mode boolean variables, we can easily toggle the presence of tasks and resources based on the selected mode, making it easier to manage complex mode logic.
  • Improve performance: Mode boolean variables will reduce the number of unnecessary computations and improve the overall performance of the system.
  • Enhance maintainability: With mode boolean variables, we can easily add or remove modes without affecting the overall sequencing logic.

How It Works

When a mode is selected, the corresponding mode boolean variable is set to true. This triggers the presence of the associated tasks and resources, which are then managed by the interval variables. This approach decouples the sequencing logic from the mode variables, making it easier to manage complex dependencies and improve the overall maintainability of the system.

Example Use Case

Suppose we have a system with three modes: mode_a, mode_b, and mode_c. Each mode has a set of associated tasks and resources, which are managed by interval variables. When mode_a is selected, the corresponding mode boolean variable is set to true, triggering the presence of tasks task_1 and task_2, which are then managed by the interval variables.

# Mode Variables
mode_a = True
mode_b = False
mode_c = False

# Interval Variables
task_1_interval = 10
task_2_interval = 20

# Task and Resource Management
if mode_a:
    task_1_present = True
    task_2_present = True
    resource_1_present = True
    resource_2_present = True
else:
    task_1_present = False
    task_2_present = False
    resource_1_present = False
    resource_2_present = False
