1. A distributed production planning and instruction apparatus, comprising:
a storage unit configured to store;
a plurality of production instructions each serving as an operation instruction for a production element including a production facility of a factory, a production resource, and an operator,
a plurality of abnormality state information including an occurrence state of an abnormality of the production element,
a plurality of production state information including state information indicating a state of each production facility and a start time and an end time,
facility-process relation information for identifying, for each process to be performed by the production element, another production element capable of alternatively performing the process;
a planning change necessity determination unit configured to, upon determining an abnormality in execution of the production instruction occurs in the production element, determine that planning change is unnecessary upon determining the production instruction can be complied in consideration of a stop period of the production element that is caused by the abnormality;
a distributed planning range calculation unit configured to include the another alternative production element in a re-planning target range; and
a distributed planning generation unit configured to re-plan the production instruction within the generated re-planning target range;
wherein when the abnormality in the execution of the production instruction occurs in the production element, the planning change necessity determination unit postpones an execution time point such that an operation is started after the stop period of the production element that is caused by the abnormality is ended, thereby allocating execution periods of all uncompleted and started production instructions in a period after a current time point, and determines that the planning change is unnecessary in a case where a scheduled start time point of a next process can be complied, and
wherein the uncompleted and started production instructions are identified by:
determining, for each of the plurality of production instructions, whether completion information, indicating that the production instruction is complete, is blank, and determining, for each of the plurality of production state information of facilities determined to be uncomplete, whether the state information indicates production has started, and reflecting the start time and the end time in the production instruction for the corresponding production facility.
