            9.   The  reformulation  of  the  information  within  the  project  description  in  terms  of  Notes
                 ……………… and variables.
            10.  The ……………… model may, in reality, be a collection of partial models each capturing
                 some specific aspect of the SUI's behavior.
            11.  The essential requirement  for the  ……………… phase  of a  modelling and  simulation
                 project is an executable computer program that embodies the conceptual model.
            12.  The simulation model is the ……………… stage of a development process that began with
                 the decision to formulate a modelling and simulation project to  resolve an  identified
                 problem.
            13.  Convenient programming constructs to deal with these various tasks are normally provided
                 in software environments specifically designed to support the ……………… activity.

            14.  Systems have a structure that is defined by its ……………… and processes.
            15.  Functional relationships can only occur because of the presence of a ………………

            1.11 Review Questions

            1.   Outline the essential steps involved in carrying out a modelling and simulation study.

            2.   Analyze how conceptual model  turns out  to be  the basis for the development of the
                 simulation model.
            3.   Examine the impact  of validation phase and experimentation phase on modelling  and
                 simulation process.
            4.   Modelling is a constructive activity and this raises the natural question of whether the
                 product (i.e., the model) is ‘good enough.’ Comment.
            5.   What do you think would be the main factors regarding Inventory Control Simulation.
            6.   Simulation software permits you to assess,  compare and optimize alternative designs,
                 plans and policies. Is this statement true or false according to you. Justify your answer
                 with proper reasoning.
            7.   The information provided by the project description is, for the most part, unstructured
                 and relatively informal. Comment
            8.   Explain the Simulation Model with examples
            9.   The model's credibility has been established, is the experimentation phase. Explain with
                 reasons
            10.  Do you think functional services can include such features as data presentation? If yes then
                 why?
