If the cost values satisfy the symmetry, such that for any I and j ? V, cij = cji, then the problem is said to be symmetric VRP, else, it is called an asymmetric VRP. In several practical cases the cost matrix satisfies the triangle inequality, such that cik + ckj ? cij for any i, j, k ? V." (Toth and Vigo, 1998, cited in Vural (2003). Vural (2003)

Salee Company Limited suffers this setback. Therefore, it should align itself in a position to maximize profits by looking in to the ways of reducing the loss. Mr. Somsak Pruksawan of the Salee Industry Public Company Limited admits that every organization, large or small businesses suffers various types of obstacle when performing businesses.

Successful supply chain strategies will consider many factors besides price; such as quality, reliability, stability, how well their technology integrates as well as plethora of other strategic considerations. Therefore since many of these factors are intangible in nature it is hard to quantify and contrast alternate supply chain possibilities. For example, if a low cost leader supplier isn't able to meet deadlines consistently then the costs associated with the

(Bienstock, 1996) These are stated to be the reason that these systems "lend themselves to investigation using simulation methodology." (Bienstock, 1996) Simulation is stated to offer an alternative "for understanding these systems, since experimenting with the actual systems would be too costly." (Bienstock, 1996) Furthermore, simulation is stated to facilitate the "examination of dynamic processes or systems over time by allowing the compression of real time." (Bienstock, 1996) Bienstock states

Logistics Case Benchmarking methodology A benchmark is defined as an agreed upon or standard reference point that is utilized to measure quality or value. In the business environment, the benchmarking process is a process through which a company agrees upon standards to measure its progress. The benchmarking process can be used both externally and internally. There are two fundamental parts of a benchmarking process, namely: performance assessment and continuous improvement. There are

TRANSPORTATION & LOGISTICS FIELD -- Challenges Issues, and Trends in the Logistics and Transportation Field The complexity of logistics in terms of the split channels, a higher variance in products and demand for customer focused solutions has been on the rise. There have been several trends that indicate that there are many challenges down the line as global trade becomes even more interactive and complex (Editorial Staff, 2013). Trends Studies point to the following
