CPM is a widely used scheduling technique for projects with well-defined tasks and dependencies. It helps identify the critical path, which is the longest sequence of tasks that determines the project's overall duration.

The primary objective of scheduling in project management is to minimize the project's duration while considering constraints such as resource availability, task dependencies, and deadlines.

EDF is a scheduling algorithm designed for real-time systems where tasks have deadlines. It prioritizes tasks based on their deadlines, ensuring that tasks with earlier deadlines are executed first.

In a Gantt chart, the bars represent the durations of tasks. The length of each bar corresponds to the estimated time required to complete the task.

Dispatching rules are a set of heuristics used for job shop scheduling. They determine the order in which jobs are processed on each machine, considering factors such as job priority, processing time, and machine availability.

Resource leveling aims to balance the allocation of resources across different tasks and time periods. It helps avoid resource overallocation and underallocation, ensuring that resources are utilized efficiently throughout the project.

SJF is a scheduling algorithm that prioritizes shorter jobs over longer jobs. It aims to minimize the average waiting time of jobs by processing shorter jobs first.

Float or slack time represents the amount of time a task can be delayed without affecting the overall project duration. It provides flexibility in scheduling by allowing tasks to be rescheduled or adjusted without impacting the project's completion date.

CPM is a scheduling technique specifically designed for projects with precedence constraints. It identifies the critical path, which is the sequence of tasks that determines the project's overall duration, and helps optimize the project schedule.

The primary difference between deterministic and stochastic scheduling lies in the treatment of task durations. Deterministic scheduling assumes that task durations are known with certainty, while stochastic scheduling considers task durations as uncertain variables.

Safety time is a buffer added to task durations to account for unforeseen delays and uncertainties that may arise during project execution. It helps mitigate the impact of unexpected events and ensures that the project is completed on or before the scheduled date.

Parallel Processing Scheduling is a specialized scheduling technique used for scheduling tasks on parallel processors. It considers the availability of multiple processors and assigns tasks to them in a way that optimizes the overall execution time.

A precedence diagram is a graphical representation of the dependencies between tasks in a project. It helps visualize the relationships among tasks and identify the tasks that must be completed before others can start.

Material Requirements Planning (MRP) is a scheduling technique specifically designed for manufacturing environments. It helps plan and schedule the production process by considering factors such as material availability, lead times, and production capacity.

In a resource-constrained project scheduling problem, the primary objective is to optimize resource utilization by assigning tasks to resources in a way that minimizes idle time and maximizes resource productivity.
