Mitsubishi Kasei and Mitsubishi Petrochemical merged to become Mitsubishi Chemical in 1994 making it the largest chemical company in Japan. This created an opportunity for improving their production systems especially for those production sites that are physically built next to each other. Mitsubishi Yokkaichi production site is a typical example, which consisted of three production sites in th...

They are all part of a safety training programme that encourages businesses in industrialized countries to share knowledge about health, safety and the environment (HSE) with developing nations. Zhang, a senior engineer in the Safety Technical Department of China Petrochemical Company (SINOPEC) lost his father in a construction accident and bears his own scars from work incidents. His visit to ...

In this comparative case study research, we reflect on two enterprise resource planning (ERP) implementation stories at two large petrochemical companies in China. These companies implemented the same ERP system in a similar time span (though not at the same time). They are two very large Chinese State-Owned Enterprises (SOEs) and in this paper we highlight the centralization versus decentraliz...

We present a study of some organizational properties of the oil transport network of the Mexican oil company (PEMEX) in a region of the State of Tabasco. Particularly, the generalized centrality and the distribution of connectivities are calculated in order to evaluate some aspects of the structure of the network. We find that the connectivities (k) are characterized by a degree distribution wh...

A nonlinear bounded PI control for inventory level regulation, and for production and incoming rate synchronization in linear dynamic supply chains is proposed. Control boundedness is required to satisfy physical and operational limitations. The control varies and synchronizes the production and incoming rates while regulating the inventory levels. The dynamic models allow reckoning multi-produ...
