It is good also as a structure which eliminates the power shortage in the area by issuing.
  • the resource accommodation method of the present embodiment when a normal business plan or facility use plan changes or when the plan is changed according to a request and the power interchange is executed, it can be obtained in the past history or request negotiation process. It is possible to predict the possibility of change of the plan from the response of the other business operator and to highly predict the flexibility of the other business operator. As a result, highly accurate power interchange can be realized.
  • the number of transportation objects such as passengers and cargo increases more than planned and the transportation capacity is insufficient.
  • the transportation force is reduced due to a sudden event such as a failure, the lack of transportation force is resolved by allowing transportation power to be interchanged among the plurality of transportation companies.
  • FIG. 12 is a conceptual diagram showing transportation capacity accommodation which is an example of another embodiment.
  • the railway operators 1202 and 1203 and the bus operator 1204 that provide passenger services between the same region and the same point, in the section of A station 1205 and B station 1206 where a certain operator (1202) provides passenger services If a malfunction occurs and passenger service cannot be provided, the railway operator 1203 or bus operator 1204, who can provide passenger service within the same section, will be able to provide passenger transportation by detour and increased transportation capacity by increasing the number of buses. Requests via communication channel 1211 to try to resolve lack of transport capacity and maintain passenger service levels. At that time, the railway operator 1202 as the client predicts the transport capacity of the other operators 1203 and 1204 and the behavior for the request, and issues the request with priority to the operator who is highly likely to respond to the request. In this way, we can get transportation capacity quickly.
  • This method of requesting accommodation can be realized by a method similar to the resource accommodation method shown in FIGS. For example, in the case of an increase in passengers expected in advance, such as holding an event, it is possible to take a sufficiently long negotiation period. If a sudden and sufficient negotiation period cannot be taken, such as an accident, a transportation company with a high degree of certainty and acceptance probability can be requested to ensure that it can receive transportation capacity.

Abstract

L'invention concerne un procédé de fourniture en continu de services par une attribution de ressources réalisée au moyen d'une coordination entre de multiples entités commerciales, ladite coordination concernant la fourniture de services d'infrastructure, tels que l'énergie électrique, le transport maritime et ferroviaire, lesdits services étant fournis par les entités commerciales. Dans un procédé d'attribution de ressources dans lequel, en réponse à une requête d'attribution, le point de savoir s'il faut accepter ou refuser ladite requête est évalué sur une base individuelle par l'entité qui a reçu la requête, et dans lequel la quantité et le souhait de réduction sont déterminés par l'intermédiaire d'une négociation, la détermination du destinataire de requête qui accomplira l'attribution, et la détermination du procédé de requête sont des problèmes. Les problèmes particuliers traités sont une estimation de haute précision de : un critère d'évaluation pour une attribution par différentes entités commerciales; et un procédé d'attribution possible. Des plans d'utilisation de services d'infrastructure et des plans de fourniture de services d'infrastructure sont partagés entre de multiples entités commerciales. Si une pénurie de ressources se produit, une date limite pour résoudre celle-ci par une attribution est calculée. Conformément à la durée jusqu'à la date limite, le destinataire de requête et le procédé d'attribution sont modifiés, permettant ainsi de prédire la probabilité d'une modification d'un plan d'une autre entité commerciale.
