Abstract Integration amongst various decision-making processes, such as planning, design, and operation is necessary to dynamic and flexible batch production. To achieve a batch production integration, utilization of common models used for various decision-making processes is an effective approach. From this point of view, a batch system common model as described by a Petri net is proposed. In this article, a fault diagnosis technique for batch processes is presented using information about fault propagation and the possibilities of integration of fault analysis and controller synthesis are discussed on the basis of the Petri net based common models.

A batch process is a discontinuous and concurrent process which is suitable for multi-product, small-sized production. The distinctive feature of a batch process is that various decision making processes, such as scheduling, design, operation, etc. are strongly connected with each other. Interaction among these processes is necessary to dynamically and flexibly cope with a variety of unplanned events. This paper aims at presenting a batch scheduling technique based on Petri net models and showing the possibilities of integration between scheduling and design of batch processes. For this purpose, it first views the behavior of a batch operating system as a discrete event system and presents a Petri net model to be used for scheduling, design and operation. It next formulates batch scheduling problems based on Petri net partial languages, proposes their solution technique and last discusses the integration between scheduling and design of batch systems.

Batch control is characterized by procedural control that is realized according to operating procedures to accomplish tasks. However, operating procedure synthesis takes considerable time and effort as the complexity of a batch process increases. To solve the operating procedure synthesis problem, a modeling technique is needed to represent the concurrent dynamics of a batch process. This paper aims at developing a method to synthesize operating procedures and procedural controllers for batch processes. For this purpose, it first views a batch control system as a discrete event system and next uses hierarchical Petri nets to represent information about process, plant, and schedule. It then presents a method to synthesize operating procedures. It also discusses the verification of synthesized operating procedures and last presents a method to synthesize procedural controllers.

Abstract The profitability of the batch processes to produce high value added product for a respective use depends greatly on the lead time from the product development to the commercial production. To shorten the lead time, integrated information support environment which enables to fully utilize the past experiences on commercialization of new products is indispensable. However, the commercialization form product development is carried out implicity in practice. Therefore, it cannot clarify how experience of the past commercialization should be repreeented as information model to shorten the lead time for a new product. In this study, an engineering activity of “commercialization of a new product in batch process” is modeled explicity by using IDEF0 expression. The sub-activities, which constitute the commercialization, and information necessary for these sub-activities can be defined hierarchically, and the required information model to shorten the lead time is able to be specified.
