Pallets are among the most used returnable transport items (RTIs), and they critical assets for a supply chain as have significant environmental economic impacts during their whole life cycle. Differently from other packaging products, pallets specifically designed to be repeatably repaired reinjected use. While this environmentally is beneficial it reduces waste, can create complex interaction...

The paper develops an order quantity model with trade credit plus shortages under learning effects for deteriorating imperfect quality products. Generally, when the lot has items, inspection of a is necessary to improve lot. In this article, seller provides defective his buyer financing scheme, and after that separates whole screening process into two categories, one other non-defective items. ...

Decision support systems are becoming increasingly sophisticated (e.g., being machine learning-based), attempting to automate decisions as much possible. However, it remains challenging extract meaningful value from large quantities of data while also maintaining transparency in seeking justification for the choices made. Instead creating methods increasing interpretability black box models, on...

The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap items are possible, these assumptions will underestimate the actual required quantity. The objective of th...

In this thesis, companies using returnable plastic packaging are investigated from a green logistics’ perspective, focusing on the washing process performed after they are used. Returnable plastic boxes used to carry components are, in some cases, washed systematically to secure customer requirements. The purpose of this master thesis is to describe existing flows of returnable plastic boxes by...

Food availability is expected to trigger hibernation and torpor (ie heterothermy) use. Yet, laboratory experiments under controlled conditions dominate, and this hypothesis remains largely untested under natural conditions. Further experimental manipulations of food availability must therefore be conducted in the wild, accounting for other covarying environmental stressors.

The advancement of paradigms such as Industry 4.0 and cyber physical systems herald increased productivity and efficiency for manufacturing businesses through increased capture and communication of data, information and knowledge. However, interpreting the raw data captured by sensing devices into useful information for decision making can be challenging as it often contains errors and uncertai...

it is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future’s demand and their quality and quantity does not change during that period. nevertheless there are special kinds of products which deteriorate or become unusable (such as food products, alcohol, medicines, etc.). therefore if the rate of deterioration is significantly high, the imp...

This paper deals with an economic order quantity model where demand is stock dependent. Items received are not of perfect quality and each lot received contains percentage defective imperfect quality items, which follow a probability distribution. Two cases are considered. 1) Imperfect quality items are held in stock and sold in a single batch after a 100 percent screening process. 2) A hundred...
