Abstract. Conceptual model is the first abstraction of the real system and plays a role of bridge between domain expert and developer. This paper discusses the research on conceptual model. It begins with an introduction to conceptual model, and addresses the definitions of conceptual model and some conceptual modeling methods, and then discusses the conceptual model validation techniques and the applications. Finally some conclusions are concluded. Keywords: Conceptual model · Definition · Validation · Conceptual modeling

Introduction

Conceptual model is the consistent description of the real system. It is normally described and expressed by language, semantic, graph and son on which is independent of platform and simulation code. Conceptual model is the first abstraction of real system and it can narrow the discrepancies between problem domain and solution domain, which is convenient for developer and user to understand and can help them achieve the agreement on the research problem [1, 2]. During the period of abstracting real system into simulation conceptual model, conceptual model has the following meanings: (1) An effective communication tool. Through the conceptual model communication between domain expert and developer is convenient. Expert can illustrate the concepts and rules about the real system clearly and developer can grasp the requirements in order to have a proper understanding of the real system. (2) A good problem solving model. That develops the conceptual model from real system and then develops simulation model from conceptual model is easier than that develops simulation model from the system. This model reduces the difficulty of problem solution. (3) An effective method for problem solution. There are various entities involved in the simulation and modeling, the relation is so complex. Within reasonable assump‐ tions the complexity of the real system is cut down and developer can hold the core content which is relative to the character of system and is concerned by the user. (4) A method for ameliorating simulation resource. Abstraction result is dropped while the simulation model has implemented. After that the same phenomenon needs to be abstracted again which leads to poor use ratio. The construction of conceptual model can help raise the reusability [3, 4].

Definitions

Dr. Robert Sargent proposed an opinion that conceptual model can be implied into simulation VV&A and defines the conceptual model as “a mathematical, logical or linguistic expression for specific research” [5]. In this opinion, Sargent emphasizes that conceptual model is relative to application. Dr. Dale Pace defines conceptual model as “translating modeling requirements into detailed simulation spec
