The influence of expedited fabrication rate, unreliable machines, scrap, and rework on the production runtime decision in a vendor-buyer coordinated environment

Transnational manufacturing firms operate in highly competitive marketplaces. This means that they are continuously seeking ways to reduce order response and fabrication cycle times, maintain the desired product quality, manage unanticipated machine failures, and provide timely delivery to effective...
