Optimization methods in discrete-event simulation have become widespread in numerous applications. However, the methods´ performance falls sharply in terms of computational time when more than one decision variable is handled. Current assay develops an ad... see more

Context. The problem of increasing the efficiency of optimization methods by synthesizing metaheuristics is considered. The objectof the research is the process of finding a solution to optimization problems.Objective. The goal of the work is to increase ... see more

Withdrawal Kanban system, by capability of data transferring in supply chain reduces different types of the wastes such as inventories level and unnecessary movements. To achieve the aims of lean production, the parameters of the Kanban system such as the... see more

This paper presents an integrated fuzzy simulation-fuzzy data envelopment analysis (FDEA)-fuzzy analytic hierarchy process (FAHP) algorithm for optimization of flow shop facility layout design (FSFLD) problem with safety and ergonomics factors.  Almo... see more

In this paper, the effects of vibration parameters of a banana screen, i.e. frequency, amplitude and vibration direction angle, on the screening efficiency per unit time were studied using the discrete element method (DEM). The simulations were validated ... see more

The following work presents a methodology to optimize the absorption coefficients, conventionally considered as the main input parameters of room acoustical simulators. In the first place a presentation of the main characteristics of the acoustic simulato... see more

The development of multimodal hubs is a sensitive task due to numerous parallel occurring processes and external dependencies. There are already isolated solutions available that mostly suffer from a holistic approach. Based on the results of a predecesso... see more

Mathematical and simulation models of systems lay at the core of many decision support systems, and their role becomes more critical when the system is more complex. The decision process usually involves optimizing some utility function that evaluates the... see more

This study proposes a hedging rule model which is composed of a two-period reservior operation model considering the damage depth and hedging rule parameter optimization model. The former solves hedging rules based on a given poriod’s water supply weighti... see more
