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 …
‘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 …
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, …
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 …
Schedule risk is the likelihood of failing to meet schedule plans and the effect of that failure. It exists in every schedule and is impossible to predict, with complete confidence, the length of time necessary to complete an activity, meet a milestone, or deliver a system. Little information exists in the early phases of a …
A Schedule Network Analysis is a graphical representation of a schedule showing each sequenced activity and the time it takes to finish each one. It’s used to identify early and late start dates, as well as early and late finish dates, for the uncompleted portions of project schedule activities. This analysis also helps determine the …
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 …
Schedule compression 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. Schedule Compression Goals The goal of schedule compression is to shorten a project schedule …
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 …
Resource leveling is a scheduling technique that addresses the availability of resources, usually manpower and equipment. Project personnel will modify scheduled activities to accommodate resource availability or unavailability. If resources are available only in limited quantities, they will change the timing of activities so that the most critical activities have enough resources to be completed, …
