We propose mathematical programming models for solving problems arising from planning and running an energy production process based on burning biomasses. The models take into account different aspects of the problem: determination of the biomasses to produce and/or buy, transportation decisions to convey the materials to the respective plants, and plant design. Whereas the “running model” is l...

this paper presents a genetic algorithm (ga) for solving a generalized model of single-item resource-constrained aggregate production planning (app) with linear cost functions. app belongs to a class of pro-duction planning problems in which there is a single production variable representing the total production of all products. we linearize a linear mixed-integer model of app subject to hiring...

Since the limited power capacity, finite inertia, and dynamic loads make the shipboard power system (SPS) vulnerable, the automatic reconfiguration for failure recovery in SPS is an extremely significant but still challenging problem. It is not only required to operate accurately and optimally, but also to satisfy operating constraints. In this paper, we consider the reconfiguration optimizatio...

Abstract Aiming at the problem of facility layout in intelligent workshops, a collaborative optimization method and AGV path planning based on discrete event simulation (DES) is proposed. This can increase production capacity workshop by solving open-field (OFLP). First, to simplify complex constraints OFLP, mathematical programming model established. Second, hybrid algorithm proposed solve opt...

A key challenge for distributed systems is the problem of reconfiguration. Clearly, any production storage system that provides data reliability and availability for long periods must be able to reconfigure in order to remove failed or old servers and add healthy or new ones. This is far from trivial since we do not want the reconfiguration management to be centralized or cause a system shutdow...

Market-oriented production systems generally have the characteristics of multi-product and small-batch production. Dynamic virtual cellular manufacturing create cells periodically in a planning horizon to respond changing demands flexibly quickly, thus are suitable for problems market-oriented systems. In current research, we propose dynamic cell reconfiguration framework under environment with...

In a carbon-constrained world, natural gas with low emission intensity plays an important role in the energy consumption area. Energy consumers and distribution networks are linked via energy hubs. Meanwhile, reconfiguration that optimizes operational performance while maintaining a radial network topology is a worldwide technique in the electricity distribution system. To improve the overall e...

The Operating Theater (OT) is known to be a fluctuating production system. The unpredictability of populations’ needs has an impact on the required human and material resources and makes the Operating Theater a dynamic environment. Thus, the use of dynamic models is getting more realistic to solve OT Layout Problem (OTLP). While solving Dynamic OTLP, Real-life Operating Theater (OT) sizes are l...

in this paper a new method is proposed for path planning of planar manipulators amid obstacles through mathematical programming in a way that the robot’s links avoid collision with obstacles throughout their motion from an initial to a goal configuration. after inputting the workspace geometry, the shortest feasible path for the robot’s end-effector is planned toward its goal position using gen...
