Contrôle des systèmes productifs travaillant à la commande et soumis à de forts aléas

Le contrôle de gestion des systèmes productifs travaillant à la commande et faisant face à une demande fortement aléatoire ne peut utiliser les outils classiques. Une approche systémique intégrant les systèmes d’information et de pilotage et s’appuyant sur une approche simulatoire offre une instrumentation qui se révèle mieux adaptée.

Statistical engineering: the key to quality

The importance of statistical methods as a fundamental element of engineering is beginning to be recognised, though rather belatedly. Historical evidence suggests the statistical skill of engineers in the UK is lagging behind that of their opposite numbers in other countries. The lack of a sound statistical element in many engineering degree courses must be a contributory factor. A course in quality assurance embracing the techniques of applied statistics along with the principles of operations management is urgently required. A suitable syllabus is proposed.

Radiation enteropathy: prevention and treatment

Surgical considerations in the management of radiation-induced injury of the gastrointestinal tract include the prevention of future radiation injury and treatment of the complications of established chronic radiation enteropathy. At the time of operation for abdominal or pelvic malignancy, the surgeon must be aware of the indications for and techniques of postoperative radiation therapy. Careful preoperative staging and close cooperation between the surgeon and the radiation therapist should allow for the planning of measured designes to position the small bowel intraoperatively such that it will receive the minimal possible radiation exposure during the course of postoperative radiotherapy. Surgical management of chronic radiation enteropathy is concerned with treatment of the complications of obstruction, fistulization, infection and bleeding. The distal small intestine and the rectum are the areas involve most frequently. Partial obstructive symptoms are best treated nonoperatively until complete obstruction ensues on until the symptoms are incapacitating. These operations can be extremely difficult. Principles of operative management include resection (whenever feasible and safe) with primary anastomosis between healthy, nonirradiated segments of bowel. Radiation proctitis is also best managed conservatively with laser therapy of rectal bleeding and supportive care of symptomatic tenesmus. When symptoms are sufficiently severe to warrant surgical intervention, protectomy with a permanent end-sigmoid colostomy is the treatment of choice. Fistula formation and pelvic sepsis are the most challenging complications associated with radiation enteropathy and may require staged procedures for management.

Operations management perspectives and the hospitality industry

This paper examines the links between operations management principles developed in manufacturng industry and problems presented by service industries, such as the hospitality industry. The value and applicability of O.M. perspectives is discussed and several examples of recent and potential application are given.

Decision making in the motor carrier industry: A preliminary investigation

This study was a preliminary investigation of the use of operations management principles in the motor carrier industry. The primary objective was to determine the degree to which sophisticated computerized planning and control systems are used in the normal course of operations of motor carriers of various sizes. The large carriers use these methods extensively, but many of the smaller carriers do not. The results of this study identify areas where managerial decision making might be improved by using operations management methods more effectively.

An experience in Bombay with postoperative complications of hemorrhoidectomy.

Summary An analysis of postoperative complications encountered in 250 patients after hemorrhoidectomy has been presented. Basic principles of operative management are elaborated. Methods of avoiding most postoperative complications are explained.
