Additive manufacturing (AM), or nonstandard 3D printing, disseminates in more and more production processes. This changes not only the production processes, e.g. subtractive production technologies are replaced, but will in all likelihood impact the configuration of supply networks. Due to a more efficient use of raw materials, transportation relations may change and production sites may be rel...

Goods producers in Canada rely on transportation networks to move raw materials and intermediate goods among production sites and finished goods to domestic and international markets. Firms in the retail, tourism and other service sectors also depend on transportation networks to assemble supplies and goods for sale and to bring customers to their facilities. Events that disable parts of the tr...

We investigate tactical level planning problems in float glass manufacturing. Float glass manufacturing is a process that has some unique properties such as uninterruptible production, random yields, partially controllable co-production compositions, complex relationships in sequencing of products, and substitutable products. Furthermore, changeover times and costs are very high, and production...

We consider the following transportation problem with both random and fuzzy factors. There exist m supply points and n demand points. For each route between supply point and demand point, unit transportation cost is a random variable according to a normal distribution and existence possibility denoting the preference choosing this route is attached. The probability that the total transportation...
