Production Information System Design

چکیده
Production Information System (PIS) collects data from the process and outputs meaningful information to decision-making agents. This paper presents an object-oriented design approach for such PIS of Flexible Manufacturing Systems. For complexity of data modelling and database consistency, the core of this PIS is a set of objects (database) linked by semantic relationships. The access to these objects, by decision-makers or data collectors, is controlled by a class of Petri nets. In this way, the complexity of data access operations and data reliability are managed.

The Use of Housing System in the Management of Heat Stress in Poultry Production in Hot and Humid Climate: a Review
There is a gap between the population growth and protein supply in many tropical countries where per capita income is low and the majority of people consume less protein than a daily standard for recommended protein intake. Poultry egg production remains the fastest route to bridging the protein demand-supply gap in these regions. However, poultry are faced with heat stress in the tropics which...
