This paper is based on the findings from the project funded by the Ministry of Science and Higher Education of Poland. It presents the application of value stream mapping in supply chains and some inadequacy of this method for supply chain integration. Based on the findings, a new Supplier Customer Production process Integration SCPI methodology is proposed. The paper presents problems with int...

Recirculating aquaculture systems are designed to raise large quantities of fish in relatively small volumes of water by treating the water to remove toxic waste products and then reusing it. In the process of reusing the water many times, non-toxic nutrients and organic matter accumulate. These metabolic byproducts need not be wasted if they are channeled into secondary crops that have economi...

In a modern printing plant software systems are ubiquitous and indispensable. Systems for order management, production planning, and other administrative systems are implemented in software. Most, if not all, equipment on the plant floor has a software front-end that either controls the physical equipment directly or displays instructions for a human operator to interpret and execute. These sof...

In this paper we optimize the production of biodiesel using bioethanol from algae following four different transesterification paths: alkali, enzymatic and heterogeneous catalysts and supercritical conditions. The reactors are modelled using response surface methodology based on experimental results from the literature. These reactor models are implemented together with short-cut methods for th...

This paper presents issues and tradeoffs in attempting to achieve lean production by increasing productivity and reducing costs and waste while at the same time operating with resilience in the face of disruptions. A simple mathematical model of the operation of a production system is proposed, which incorporates two types of disruptive events: resource breakdowns and quality loss. The model is...

Optimal placement of scattered generator sources in the main and secondary feeders of radial grid reduces energy losses, releases the capacity of existing feeders and improves the existing voltage profile. In this project determine the location and suitable for the production of production resources S cattered in radial feeders of unbalanced distribution networks, a new formulation solution is ...

Lean production refers to approaches initially developed by Toyota that focuses on the elimination of waste in all forms. Lean has been extremely successful in large high volume manufacturers. However, many small to medium size low volume manufacturers have not fully embraced the potential benefits of a lean production system. This paper focuses on the implementation of lean in a small manufact...

The paper describes an approach for integrating planning capabilities into production scheduling. We give an abstract view of production scheduling that motivates the integration and we compare the existing solving technologies in respect to their power for planning and scheduling integration. A new formal model of production scheduling is proposed and its realization in the Visopt ShopFloor sy...

De-novo motif search is a frequently applied bioinformatics procedure to identify and prioritize recurrent elements in sequences sets for biological investigation, such as the ones derived from high-throughput differential expression experiments. Several algorithms have been developed to perform motif search, employing widely different approaches and often giving divergent results. In order to ...
