Simulation Modeling Steps

A simulation of a system is the operation of a model of the system; “Simulation Model”. The steps involved in developing a simulation model, designing a simulation experiment, and performing simulation analysis are: [1] Step 1. Identify the Problem: Enumerate problems with an existing system. Produce requirements for a proposed system. Step 2. Formulate the […]

Modeling & Simulation Support

  The use of Modeling and Simulation (M&S) in Test and Evaluation (T&E) provides test data to support system concept exploration. It provides valuable information that can increase confidence levels, decrease field test time and costs, and provide data for pre-test prediction and post-test validation. M&S in T&E can be divided into three (3) categories:

To Complete Performance Index

The To Complete Performance Index (TCPI) is a comparative Earn Value Management (EVM) metric used primarily to determine if an independent estimate at completion is reasonable. It computes the future required cost efficiency needed to achieve a target Estimate at Completion (EAC). TCPI Definition: It is a measure of the cost performance that is required

M&S Body of Knowledge

  This DoD Modeling & Simulation (M&S) Body of Knowledge (BOK) was published in June 2008. The BOK provides standardized language and associated knowledge base for users, developers, managers and executive-level personnel to effectively apply M&S to DoD requirements. The awareness and application usage levels contained in this BOK are displayed by the services (Army,

'What if' scenario analysis

‘What if’ scenario analysis is a simulation method that compares and measures the effects of different scenarios on a project schedule. It uses Schedule Network Analysis to determine the effects of various scenarios on a project schedule from delayed activities, strikes, bad weather, late resources, and other adverse situations. This analysis is used to plan

Schedule Control

Step 5: Schedule Control in the Schedule Preparation process is to identify schedule variations and to manage actual changes to the developed schedules. (see Controlling Process) A schedule change control system that defines the procedures by which changes can be made should be established and integrated into the program’s overall change control system. The schedule

Schedule Compression

Schedule compression, also known as time compression or schedule crashing, is a technique used in project management to shorten an already-developed schedule. This might be done to meet an updated delivery date, a new opportunity, or a schedule delay. It’s done without changing the scope of the program. Definition: Schedule compression is a project management

Schedule Development

Step 4: Schedule Development involves the development of realistic start and finish dates for each activity. An iterative process, schedule development takes into account activity sequencing, duration estimates, resource requirements and availability, calendars that show when work can be performed, constraints, assumptions, and risk. [1] The output of this step is a set of schedules
