Grand challenges are significant themes that can bring together researchers to bring significant change to a field. In 2012 a new initiative to restart the debate on major grand challenges for modeling and simulation (M&S) began. Leading researchers have presented M&S Grand Challenges in areas such as ubiquitous simulation, high performance computing, spatial simulation, big simulation, human behaviour, multidomain design, systems engineering, cyber systems, network simulation and education. To contribute further to this initiative, this paper presents M&S Grand Challenges from an Operational Research/Management Science (OR/MS) perspective and discusses themes including simulation in healthcare, value of information, data modeling, stochastic modeling and optimization, agent-based simulation and simulation analytics.

Vietnamese industrialists have understood that simulation studies can help to form a more reliable manufacturing line than conventional methods that for the most based upon engineering experiences. However, the use of simulation has not been applied in designing the manufacturing line, and a confident method of designing a new manufacturing line or modifying the capacity of a current manufacturing line (CML) has remained a task in Vietnamese industrial plants. The main purpose of this research is to propose a new perspective of a simulation study in Vietnamese industry from an empirical point of view to implement the framework for designing a manufacturing line. The second purpose is to introduce the method and analytical procedures of modifying a CML utilized by a linear programming (LP) model for selecting. The proposed method was applied in an actual design project to confirm the feasibility of the framework.

A simulation project is much more than building a model and the skills required for success go well beyond knowing a particular simulation tool. A 30 year veteran discusses some important steps to enable project success and some cautions and tips to help avoid common traps. This content is similar to presentations given at previous WSC conferences.

Modeling and simulating a real world scenario is fundamentally an abstraction that takes only part of the given scenario into the model. Furthermore, the level of detail in the model, a.k.a. the resolution, plays an important role in the modeling and simulation process. Finally, the abstraction and resolution of the model determine the fidelity of the modeling and simulation, which becomes the ultimate utility for the model users. While abstraction, resolution and fidelity are the corner stones of the modeling and simulation discipline, they are often casually utilized. Moreover, their interplay is not investigated in-depth with explicit operationalization of the concepts. This article operationalizes the concept of abstraction, resolution, and fidelity by focusing on the aspect of model information. This theoretic investigation answers propositions involving these concepts, i.e. whether or not a higher resolution model has higher fidelity and why, through set theoretic approaches.

complex systems contain hierarchical heterogeneous subsystems and diverse domain behavior patterns, which bring a grand challenge for simulation modeling. To cope with this challenge, the M&S community extends their existing modeling paradigms to promote reusability, interoperability and composability of simulation models and systems;however, these efforts are relatively isolated and limited to their own technical space. In this paper, we propose a domain specific modeling (DSM)-based multi-paradigm modeling approach which utilizes model driven engineering techniques to integrate current M&S paradigms and promote formal and automated model development. This approach constructs a simulation model framework to architect the structure of the overall simulation system and combines multiple M&S formalisms to describe the diverse domain behaviors;moreover, it provides domain specific language and environment support for conceptual modeling based on the model framework and formalisms. An application example on combat system effectiveness simulation illustrates the applicability of the approach.

The objective of this paper is to illustrate the application of construction schedule simulation during the planning phase of a construction project. Schedule simulations can be used to develop risk informed schedules that support improved contingency planning. This paper discusses the challenges underlying construction schedule simulation, and how they can be addressed by an interactive simulation platform such as the Interactive Construction Decision-making Aid (ICDMA). Further, the paper uses ICDMA during the planning process, for a case study, to identify the activities in a project that are most likely to change criticality during the construction process. Current scheduling techniques such as the Critical Path Method (CPM) are capable of identifying critical activities, but they cannot be used to assess the likelihood of alternative critical paths emerging during construction due to unexpected disruptions in the as-planned schedule. The research illustrates the usefulness of construction simulation in supporting the scheduling process.

An overview is presented of SAS simulation Studio, an object-oriented, Java-based application for building and analyzing discrete-event simulation models. Emphasis is given to simulation Studio's hierarchical, entity-based approach to resource modeling, which facilitates the creation of realistic simulation models for systems with complicated resource requirements, such as preemption. Also discussed are the various ways that simulation Studio integrates with SAS and JMP for data management, distribution fitting, and experimental design.

In this paper, I shall propose an integrated model of worker skills and team motivation for a computer-based simulation game that can be used to provide experiential learning to students. They can act as project managers here without being burdened by the costs and risks associated with unsuccessful projects. I shall present an approach of classifying skills into five different types (relevant to IT projects) and apply a five-point competency scale to each skill type. The Pearson Correlation will be applied to the scores of each skill type to generate an efficiency index that will characterize the effectiveness of a team working on a task. I shall also describe a model to represent the relationship between the social needs of team members and their motivation levels. The results of the actual simulation games will be presented here followed by a discussion on the practical implications and recommendations.
