With the aim of designing efficiently and quickly such plans as production plans having a variety of requirements involved and requiring frequent modification of software, a planning logic prepared without regard to the preparation sequence of a plan is converted into a planning program. Upon the conversion, the planning logic is edited so that only part of the planning logic requiring modification may be modified, and a result of modification is displayed on a screen so as to be checked through a display.

A planning method by computer support is based on a planning program using data concerning an object to be planned and data necessary for planning. The planning method comprises the steps of reading out of a memory various kinds of data concerning the object to be planned; preparing a plan by using the data in accordance with the planning program; delivering results of the prepared plan; inputting definition data for an explaining statement concerning the planning results and data concerning an output form of the explaining statement; processing the planning results on the basis of the definition data for the explaining statement and the data concerning the output form to prepare an explaining statement concerning the planning results; and delivering the prepared explaining statement.

A plurality of devices for processing IF-THEN JOIN operation of IF-THEN rules are provided to process the JOIN operation in a pipe-line manner. A JOIN operation processing facility has an input buffer for latching status data corresponding to one condition in a certain rule; an associative memory for latching status data corresponding to another condition; an output buffer for latching the result of a JOIN operation; and a data combining arrangement for replacing an item value from the two data by a meaningful value to generate one data so that a series of operations of picking up the data one by one from the input buffer, retrieving associatively the data of the associative memory by using the data picked up as a retrieval data and the common item as a retrieval key, and storing in the output buffer the combined result of the data picked up and the retrieval data.

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.

In a method for determining an optimum scheduling in a computer-aided scheduling system the data associated with a schedule to be generated is previously stored in a memory data. A strategy decision table showing therein one or more scheduling strategies suitable for a plurality of the states in a scheduling process is prepared. An optimization definition table indicating degree of improvement precedence or precedence order of the scheduling strategies of the evaluation items, where degree of improvement precedence is defined as degree of improvement of evaluation value of he evaluation item in changing of the scheduled strategy, is prepared. A schedule is generated by repetition of selecting and executing the scheduling strategies by using the strategy decision table. The other schedules are generated by changing the scheduling strategy selected in the state of the scheduling process by using the optimization definition table. An optimum schedule having the best evaluation value is selected.

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.

An aromatic polyimide film favorably employable for the chip-on-film (COF) system is composed of a polyimide derived from 3,3′,4,4′-biphenyltetracarboxylic acid dianhydride and p-phenylenediamine and a powdery inorganic filler, in which the film has a thickness in the range of 25 to 35 μm and does not have protrusions of 1 μm or higher, and the filler has a mean diameter of less than 1 μm.

A tetraester of 3,3′,4,4′-biphenyltetracarboxylic acid is advantageously prepared by a process composed of a step of dimerizing an o-phthalic diester in the presence of a catalyst comprising a powdery palladium salt having a specific surface area of at least 0.5 m2/g and a basic bidentate ligand compound and one or more steps of continuing the dimerization after supplemental addition of at least one of the powdery palladium salt and the basic bidentate ligand compound.

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.
