Focus group interviews were conducted at a large steel manufacturing company with 1000 employees, in order to answer the research question: what is the safety culture and risk-taking like at the company, according to employees? Ten focus groups were used for data collection consisting of 6-8 employees each. The participants were operators from production. The interviews lasted 75 min and were d...

Mollenberg-Betz was founded in 1910 by Henry J. Mollenberg and Jacob Betz as a machine shop serving nearby shipping, steel mills, and other industries.

This study proposes a materials procurement contracts model to which the zero-cost collar option is applied for heading price fluctuation risks in construction.The material contract model based on the collar option that consists of the call option striking zone of the construction company(the buyer) following the materials price increase andthe put option striking zone of the material vendor(th...

The steelmaking process consists of two phases: primary steelmaking and finishing lines. The scheduling of the continuous galvanizing lines (CGL) is regarded as the most difficult process among the finishing lines due to its multi-objective and highlyconstrained nature. In this paper, we present a multi-population parallel genetic algorithm (MPGA) with a new genetic representation called k near...

This paper presents three prototypical expert systems that were developed in different fields of the steel making industry. It is described which kind of knowledge has to be represented, what are the techniques required for intelligent reasoning, and why expert systems offer better solutions to the described problems than traditional programming approaches. From the given applications the main ...

a r t i c l e i n f o We introduce a multiple scenario, multiple period, optimization-based decision support system (DSS) for strategic planning in a process industry. The DSS is based on a two stage stochastic linear program (SLP) with recourse for strategic planning. The model can be used with little or no knowledge of Management Sciences. The model maximizes the expected contribution (to pro...
