Using a Discrete-event Simulation Model for Efficient Operation of Tunnel Boring Machines Mohammad Mahdi Farshchian, Gholamreza Heravi

A tunnel boring machine (TBM) is the primary resource in a tunnel construction project and generally its advance rate is equal to the performance rate of the whole project. Regarding previous studies, the utilization factor of TBMs is approximately 50% most of the time. The process of repair and maintenance of various parts of the machine and the logistic equipment takes 50% of the time. The model presented here, tries to simulate the whole process of tunneling in Ahwaz Urban Railway project, in Iran, that contains two 23 km long tunnels and find out how impairment of different parts of the TBMs can delay the project.

Analysis of Alternative Approaches to Chipotle Mexican Grill’s Service System Using Discrete Event Simulation Brad Guthrie

Chipotle Mexican Grill is a fast causal restaurant chain headquartered in Denver, Colorado. Founded in 1993, they now have over 1,700 locations across America, as well as internationally. Their product line consists of 4 entrée types, 5 protein types, 2 selections of both rice, and beans, 4 types of salsa, and a small selection of extra toppings. Although the “integrity” of their food is a fundamental part of their business strategy, according to both of their co-CEO’s, throughput is also a key factor of focus.

Major City Evacuation Planning Using Simulation Modeling A, Kirby, J.E. Dietz, E. Matson, J. Pekny, C. Wojtalewicz and J. Pekny

Disaster, whether manmade or natural, can have a catastrophic impact on a populated area. Sometimes, the disaster is so devastating that it requires a large-scale evacuation. As a result, evacuation plans have become a necessity. One such evacuation plan is the regional hub reception center (RHRC), which will help evacuate the careless population when an evacuation is needed. Using AnyLogic as a simulation modeling software, an RHRC model was developed to test the efficiency of the proposed plan.

Simulation Software Comparison Based on ORMS Today-2015 Comparison

The comparison of AnyLogic and other simulation tools is inspired by ORMS Today Simulation Software Survey published in October, 2015. “ORMS Today” journal, published by a global institute of operational management and analytics “INFORMS”, completed a detailed comparison of popular tools for discrete-event modelling. In 2015 it was supported by 31 developers and 55 tools. Data, used in the research, was kindly presented by the developers themselves.

Evaluation of Agent-Based and Discrete-Event Simulation for Modeling Construction Earthmoving Operations E. Zankoul, H. Khoury and R. Awwad.

One of the most common operations to any construction project is earthwork. In fact, most, if not all, construction projects begin with earthwork activities. These activities require heavy equipment, are generally quite costly and consume a considerable amount of time.

Towards a Semiconductor Supply Chain Simulation Library (SCSC-SIMLIB) Jingjing Yuan, Thomas Ponsignon, Infineon Technologies AG. Winter Simulation Conference, 2014.

Simulation is a widely used technique for analyzing and managing supply chains. Simulation software packages offer standard libraries for selected functions and application areas. However, no commercial or freeware simulation tool proposes building blocks specific to semiconductor manufacturing.

Jobsite Logistic Simulation in Mechanized Tunneling M. Scheffer, T. Rahm, R. Duhme, M. Thewes, M. König, Ruhr-Universität Bochum. Winter Simulation Conference, 2014.

Projects in mechanized tunneling frequently do not reach their targeted production performance. Reasons are often related to an undersized or disturbed supply-chain management of the surface jobsite. Due to the sensitive interaction of production and logistic processes, planning and analyzing the supply-chain is a challenging task.

Discrete Choice, Agent Based and System Dynamics Simulation of Health Profession Career Paths T. Flynn, Y. Tian, K. Masnick, G. McDonnell, E. Huynh, A. Mair, N. Osgood. Winter Simulation Conference, 2014.

Modelling real workforce choices accurately via Agent Based Models and System Dynamics requires input data on the actual preferences of individual agents. Often lack of data means that analysts can have an understanding of how agents move through the system, but not why, and when.

A Hybrid Simulation Approach to Dynamic Multi-Skilled Workforce Planning of Production Line Yuan Feng, Wenhui Fan, Tsinghua University. Winter Simulation Conference, 2014.

Workers cross-trained with multiple tasks can improve the workforce flexibility for the plant to handle
variations in workload. Therefore, it is necessary to study the dynamic multi-skilled workforce planning
problem of production line with the application of cross-training method.

Iterative Simulation and Optimization Approach for Job Shop Scheduling Ketki Kulkarni, Jayendran Venkateswaran, Indian Institute of Technology Bombay. Winter Simulation Conference, 2014.

In this paper, we present an iterative scheme integrating simulation with an optimization model, for solving
complex problems, viz., job shop scheduling. The classical job shop scheduling problem which is NP-Hard,
has often been modelled as Mixed-Integer Programming (MIP) model and solved using exact algorithms (for
example, branch-and-bound and branch-and-cut) or using meta-heuristics (for example, Genetic Algorithm,
Particle Swarm Optimization and Simulated Annealing).
