SMA Project Lifecycle Roles - Assignment Example

The modeling path begins with the development of a conceptual model. The conceptual model covers the objectives, the inputs (experimental factors) the model content, and the outputs (responses).

The purposes of a simulation model are:
- Captures the key elements in the system and their relation­ships.
- Its purpose is to document how the system works.
- Provide an understanding of how detailed the model needs to be to meet the analysis objectives.
- Identify data needs.
- Uncover possible modeling challenges.

The conceptual model is a key means of validating the simulation model and addressing whether the right model is being built. Validation determines whether the model is a meaningful and accurate representation of the real system.

The programmed model used for experimentation is a translation of the conceptual model into computer-executable form. Before experimentation, the programmed model must be verified to determine that it is working as intended. This step focuses on building the model right according to specifications.

Conceptual modeling - Model formulation since it’s a conceptual representation of the system which captures the key elements in the system and their relationships and documents how the system works:
- Validation since it seeks to answer if the model meets the analysis objectives by identifying data needs and specifications.
- Data preparation and collective analysis which is used in the identification and collective analysis of needs.
- Design experiments that can uncover modeling challenges after understanding how the system works.

Programmed model-Model translation involving pilot runs since it translates the conceptual model into computer executable form:
- Verification which determines whether the developed system is working as intended.
- Experimenting since it involves the execution of the developed model to check its preliminary performance.

The model and project need to be documented throughout the process and not delayed until the end. Project management emphasizes the need to use good project management practices throughout the study.

Modeling involves characterizing input data as probability distributions. Models are developed through commercial simulation software packages available in the marketplace. The reasons for building models are to conduct analyses, increase understanding and obtain results.

The role of a user in a simulation model is verification of the model. Since the model is developed to meet the user's requirements, the user is responsible for verifying if the system meets his demands.

Simulation modeling analysis involves identifying the purpose of the model, designing the model by studying the inputs and the expected outputs, and translating the model into computer executable form which is then concluded by the implementation of the model; putting the model into use.
