The determination of the optimal carrying capacity procurement of rail and shipping services in the automobile intermodal network with unique characteristics is essential to save automobile delivery cost. In this research we develop a two-stage stochastic programming model for the tactical-level decision problem arising in the special automobile intermodal network. Furthermore, we improve the s...

plants polluted with pb produced by automobiles along the roads and highways have extensively been reported all over the world. it is the most important source of pollution in the environment. this research was carried out to determine the polluting degree of plants along the highways such as: rasht-anzaly, kelachay-ramsar, tehran-karaj, and isfahan-tehran. at each arbitrary point, a transect 1...

The goal of this paper is to propose a tabu search heuristic for the car sequencing problem (CSP) used for the ROADEF 2005 international Challenge. This NP-hard problem was proposed by the automobile manufacturer Renault. The first objective of the car industry is to assign a production day to each customer-ordered car and the second one consists of scheduling the order of cars to be put on the...

There are only few studies about the relationship of skin lesions and the percutaneous uptake of hazardous substances in exposed workers. Several aromatic amines are well known carcinogens for humans and/or animals. This case report emphasizes the relevance of dermal absorption of the aromatic amine ortho-toluidine considering four workers with different skin status (healthy, erythematous and b...

A color change occurs in a solution to Problem 1 whenever adjacent letters of w differ in color. The number of occurences of each element of Σ in w is not prescribed in the general form of the problem, where it can be seen as the problem of sequencing products (the elements of Σ) so that the production sequence is maintained and contains a minimal number of color changes (an application can be ...

The objective of this study is to develop an intelligent action algorithm for virtual human agents on three-dimensional large terrains to accomplish a specified mission by group communication and coordination. The area contains natural and build-in entities such as trees, rocks, rivers, roads, houses, bridges, etc. Our platoons that are represented by virtual human agents enter a specific area ...

Today, planning and control of logistic processes on automobile terminals are generally executed by centralised logistics systems, which in many cases cannot cope with the high requirements for flexible order processing due to increasing dynamics and complexity. The main business processes on automobile terminals – notification of vehicles by automobile manufacturer, transport to automobile ter...

China’s automobile industry has made great progress and contributed a lot to national economic development, but the problems such as dispersion, small, disorderly, worse" in the industry is still very serious. Starting from the SCP paradigm theory in China’s automobile industry, the article analyses the problems including the market structure, market conduct and market performance in China’s au...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...
