Embodiments of the present invention provide a production planning method and system. Where a manufacturing apparatus is shared by a plurality of products in a production line, if a manufacturing (production) availability number is changed, a cause parameter is automatically investigated so that a production plan with high precision can be prepared in a short time. With respect to a production plan as the previous/current comparison objects, a production process used in the production plan in which a change occurs, is extracted. From the production process, a parameter item to be used in the production capacity evaluation is extracted for all products, a difference comparison is made between the value of the previous parameter and the value of the current parameter, so that the parameter item as the cause is specified. The combination of the cause parameter items is calculated, and a cause parameter list is prepared. Next, from the specified parameter list, the parameter item is sequentially changed, and the manufacturing (production) availability number is recalculated. An influence index given to the manufacturing (production) unavailability number by the cause parameter, is calculated.

A membrane filter of 0.025 to 0.05 .mu. in pore size is treated by passing the solution of a water-soluble high molecular substance such as albumin, dextran, polyvinylpyrrolidone, polysorbate 80, gelatin or the like through the membrane filter. Employing the filter thus treated, the solution of a physiologically active substance of human origin such as human growth hormone, kallikrein, trypsin inhibitor, epidermal growth factor, leucocyte interferon etc. is filtered at high recovery rate of the active substance avoiding the adsorption of the active substance onto the filter. By the filtration, harmful viruses such as Creutzfeldt-Jacob disease pathogen which may exist in the physiologically active substance can be removed.

摘要:
A transportation schedule planning support system receives an order of one or more types of products which requires a use-by date control, and transports the products from one or more stock-carrying bases to one or more delivery destinations. In the system, a user previously registers a transportation route candidate from a stock-carrying base to each delivery destination adoptable as a solution, as a base group. A necessary use-by date for a product to be delivered next is determined based on an actual delivery to each delivery destination. The number of vehicles allocatable to a transportation at each base according to a vehicle type, and a vehicle type not used in each base group are added to a restriction condition. A mixed integer programming is applied using an expected obtainable profit obtained by delivering each product as an objective function.
