摘要： A control system employs a controller for controlling the operation of a plurality of facilities and a memory which stores information employed by the controller for controlling the operation of the facilities. The memory includes a first portion for storing facility status signals and command signals, a second portion which stores a series of rules which are triggered in response to status information from the respective facilities, a portion which converts the rules into internal codes, and a portion which stores the results of the application of the internal codes to control commands. The controller monitors facility status signals and controls the generation of facility status signals. It also controls which rule set number is to be used in accordance with information stored in memory and contains an internal code generator for generating the internal codes corresponding to generated facility status signals. The controller reads out rules from memory based upon the rule sets being employed and generates control command signals in accordance with data stored in memory. From these signals, command signals are generated for controlling the operation of the facilities.

摘要： In order to execute a series of moving sequences by synchronous and exclusive control of unit operations taught or programed in advance, there are provided a first storing of the relationship of the sequence of execution of each unit operation to other unit operations to be controlled synchronously or exclusively; a second storing of information relating to the operational status of each unit operation; and a third storing of operating instructions for executing each unit operation. When machine tools have stopped due to the occurrence of an abnormality while a series of unit operations are being executed by the operating instructions stored in the third storing means, a unit operation for restarting on the basis of the relationship of the executing sequence stored during the first storing is appointed, and information concerning the operational status stored during the second storing is corrected. Furthermore, at the time when a junction operation in which there exist two or more sequences leading to a unit operation has been executed, a fourth storing is effected during the normal state of the operation steps relating to that execution. Then the content of the information stored during said second storing is corrected to a state permitting restarting from an appointed unit operation by referring to information stored during the fourth storing.

摘要： A job scheduling method for scheduling of job allocation to various resources, wherein each workload of a job is allocated to each time unit along a time axis in units of job and resource type. Based on the workload allocated in units of resource type, an initial workload for all resources at each time unit is calculated. A first workload balancing is performed for an initial workload at a time unit exceeding a resource capacity so as to balance the initial workload within the resource capacity. Thereafter, a second workload balancing is performed so as to balance a workload allocated in units of resource type within its resource capacity.

摘要： A condition-responsive control arrangement for facilities, e.g in an automated factory, provides for receiving status signals from the facilities and delivering command signals responsive to the status signals to the facilities. Upon the generation of a status signal, the identity number of a rule set (control logic) for use is determined; a corresponding internal code (Fig. 3b) is generated from the status signal on the basis of look-up data stored in memory means; the corresponding coded rules are read out from another memory means on the basis of the identity number of the rule set; the internal code of a final control command is decided by referring to a further memory means (50, Fig. 5B) which stores codes of conclusions formed on the basis of the coded status signals and the applied coded rules; and the command signal for a facility is generated from the internal code of the decided control command by referring to the stored look-up data. The use of internal codes provides faster data processing than in prior art arrangements using character strings.

摘要： An automated ordering system in a retail shop adapted to automatically order goods. In the system, a demand amount in the future is first supposed on the basis of an average of the past demands, the supposed future demand amount is corrected by the variable condition used to change the demand amount to predict a future demand amount, and the order amount is determined pursuant to a calculation formula on the basis of the predictive future demand amount and the stock volume of goods. Goods tend to be stocked in surplus or out of stock are diagnosed on the basis of the change of the past demands and the worker determines the amount of orders in respect to these goods.

摘要： In order to execute a series of operation sequence including synchronization and exclusion for an automatic machine such as a robot by combining pretaught or preprogrammed unit operations, there are provided first memory for storing a start sequence of the unit operations to be synchronized or excluded, second memory for storing operation status of the unit operations and third memory for storing operation command to start the unit operations. The unit operations to be started are determined by referring the start sequence and the operation status of the unit operations read from the memories, and the corresponding operation commands are read out of the third memory to sequentially start the unit operations. In order to execute an repetitive operation of similar works, there is provided fourth memory for storing basic operation patterns common to the repetitive operation in a non-repetitive manner. Further, sub-parameters are generated as many as the number determined by the number of times of repetition required and the content of operation, desired operation content is selected in accordance with the stored basic operation patterns and the generated subparameters, and the selected operation content is executed as many times as the number of sub-parameters, and the number of times of execution of the basic operation pattern executed is counted at an end of a repetitive section.

摘要： A multi-facility control system includes a controller and attendant memory. Stored in the memory are a plurality of rules, each of which includes a conditional portion representative of a condition to be examined and a conclusive portion describing action to be taken when the condition is satisfied. Also stored in memory is the current status of each facility, information representative of the tasks to be performed by the facilities and updated status information resulting from the satisfaction of the conditional parts of the rules. The controller monitors the status of the facilities and compares monitored status information with the conditional parts of the rules stored in memory. When rule conditions are satisfied, control instructions are generated which are employed to produce command signals that are coupled to the respective facilities for controlling the operations thereof.
