A Survey of Transportation Problems

This paper aims at being a guide to understand the different types of transportation problems by presenting a survey of mathematical models and algorithms used to solve different types of transportation modes (ship, plane, train, bus, truck, Motorcycle, Cars, and others) by air, water, space, cables, tubes, and road. Some problems are as follows: bus scheduling problem, delivery problem, combining truck trip problem, open vehicle routing problem, helicopter routing problem, truck loading problem, truck dispatching problem, truck routing problem, truck transportation problem, vehicle routing problem and variants, convoy routing problem, railroad blocking problem (RBP), inventory routing problem (IRP), air traffic flow management problem (TFMP), cash transportation vehicle routing problem, and so forth.

Surveying the Optimization Problems of Water Distribution Networks

This paper aims to guide understanding of the different types of optimization problems of water distribution networks by presenting a survey of mathematical models and algorithms used to solve the variants of said networks. Problems include water resource planning, water quality management, water supply networks, water distribution systems, water flow and chemical transport, and water distribution network. Optimizing resources to transport water is an issue of global interest and is important to minimize the costs of construction of pipeline to supply water, repair costs, and water transportation.

MISMA: An Approach to Mexican Information Security Methodology and Architecture for PYMES

In Mexico the computer science security is growing, but not therefore the initiatives of law nor the standards in the matter of computer science security, although they exist international standard of computer science security the recommendations are not adopted due to infrastructure differences and that contain there, and that cannot be adopted by the Mexican companies. The main idea to propose a methodology and architecture for the small and medium companies is with the purpose of providing a tool that allows the companies to count on basic a computer science security system that allows diminishing the security problems.
