This study addresses a stochastic structure for generation companies (GenCoʼs) that participate in hydro-thermal self-scheduling with a wind power plant on short-term scheduling for simultaneous reserve energy and energy market. In stochastic scheduling of HTSS with a wind power plant, in addition to various types of uncertainties such as energy price, spinning /non-spinning reserve prices, unc...

This paper proposes a modified spring modeling algorithm for drawing undirected graphs, that is an extension of the forceddirected placement method of spring modeling algorithm by Eades. We call it dynamic parameter spring modeling algorithm. This algorithm is not only a general algorithm for graph layout, but also it is more suitable to get a semi-stable graph layout. A semi-stable layout is a...

Network diagrams are a familiar graphic form that can express many diierent kinds of information. The problem of automating network-diagram layout has therefore received much attention. Previous research on network-diagram layout has focused on the problem of aesthetically optimal layout, using such criteria as the number of link crossings, the sum of all link lengths, and total diagram area. I...

Grouping the machines and parts in a cellular manufacturing system based on similarities is known as the cell formation. This paper proposes a method for design of cell layout for a manufacturing system under dynamic demand environment for automation batch production industry. The proposed method of cell layout has two phases. In the first phase, Rank Order Clustering (ROC) was used to determin...

In this paper, a mixed-integer linearized programming (MINLP) model is presented to design a group layout (GL) of a cellular manufacturing system (CMS) in a dynamic environment with considering production planning (PP) decisions. This model incorporates with an extensive coverage of important manufacturing features used in the design of CMSs. There are also some features that make the presented...

tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. the tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. this problem has already been so...

This paper proposes a methodology for the layout selection of an urban drainage system as extension to optimal sewer network design proposed by Duque, Aguilar, & Saldarriaga. The approach in this uses objective function that takes into account all input data problem, such as: land topography, street topology, and inflow each manhole. Once is selected, optimally designed using dynamic progra...

This paper is on the aesthetic layout of n-ary trees with nodes of variable size, also referred to as generalized box-drawing. For this layout problem a few algorithms have been proposed, which differ in their runtime performance and the attained aesthetic criteria. We introduce a new approach to this layout problem, which is interesting because of both its simplicity and elegance, and which em...

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...
