摘要： In a computer system for parallelly executing a plurality of tasks by sharing a plurality of resources in a data base of a computer, a use sequence of the resources to be used by each task is inputted to the computer prior to the execution of the tasks. A possibility of deadlock due to sharing of common resources amojng the tasks is checked based on the information on the use sequence, and a deadlock avoidance information table is prepared. When the task issues a start request, the deadlock avoidance information table is referred and the start of the task which has the possibility of the deadlock is delayed.

摘要： PROBLEM TO BE SOLVED: To obtain a graphic user interface which can search and display various kinds of data of many facilities in a large-scale system with less screen hopping and simple operations. SOLUTION: When 'SYSTEM MONITOR' is selected, an electric power station tree diagram display screen 401 and a monitored data display screen 402 are displayed, and the latter is divided into a monitored data list screen 402-1 and a particularly-monitored data display screen 402-2. Electric power station selecting TAB (4)-1 and data selecting TAB (4)-3 are each provided on the display screens 401, 402. When 'SYSTEM' is selected in the selecting TAB (4)-1, an electric station tree diagram (4)-2 grouped (controlled in a folder) in accordance with the connection of systems is displayed from the upper rank of voltage classes. For example, when an arbitrary electric station (500 kV-A1s/s) is selected in the electric station tree diagram (4)-2 and 'TM' is selected in the data selecting TAB (4)-3, the list of TM data of the A1s/s is displayed on the screen 402-1. By selecting the data of an arbitrary line from the list, a trend graph is displayed on the screen 402-2. The selecting TABs (4)-1, (4)-3 can each be selected independently.

摘要： PROBLEM TO BE SOLVED: To efficiently generate a program, especially a performance simulation program for evaluating a computer system. SOLUTION: Simulation parts for realizing a unit job specified in advance are provided in a storage device 205. A job simulation part 201 generates a processing procedure file in which the processing procedure in executing a desired job is defined by the unit job. The processing procedure file can also be obtained by retrieving a database 202 by a retrieving part 203. A performance simulation part 204 generates a job flow definition file by combining the simulation parts according to contents described in the processing procedure file. A compilation part 210 generates the program by compiling the job flow definition file.

摘要： PURPOSE:To prevent the generation of deadlock by extracting the using order of resources by a program compiler for plural programs using plural resources in common and previously extracting the existence of generation of deadlock on the basis of the extracted information. CONSTITUTION:The access order of resources 9 in a data base 5 is extracted by the compiler 7 and stored in a resource occupation table 10. At the time of ending the compilation of all source programs, a deadlock checking table 12 and a table 13 corresponding to task groups to be used for an execution control mechanism 14 are formed by means of a table generator 11. At the time of operating a task group 8, the mechanism 4 receives information for occupying/releasing resources and schedules tasks so that no deadlock is generated between the tasks on the basis of information stored in the tables 12, 13 and a group state table 16.

摘要： PURPOSE:To eliminate data transfer between files and to attain a smooth design work by providing a buffer storing data which adds, deletes and updates a recording instead of work files. CONSTITUTION:The buffer 100 is provided temporarily storing data which adds, deletes and updates record on a design data file 400. Record is read from a first storage area 200 in said file 400 in key order, and information on input and editing data on the buffer 100 is compared. If it coincides with key information of the deleted data of the record, the record read from the area 200 is not written in a second storage are 300. If it coincides with key information on the update data of the record, the data on the buffer 100 is written in the area 300. If it coincides with the additional data of the record, the data on the buffer 100 is written in the area 300 when key information on the buffer 100 is smaller than that of the record in the area 200.

摘要： PROBLEM TO BE SOLVED: To provide a system which enables maintenance to be performed without paying attention to the finish timing of the installation of local equipment in a system for maintaining the equipment date of an electric power monitoring and controlling system. SOLUTION: When local devices 1 to N are connected to an electric power system monitoring and controlling computer system 9 via a remote monitoring device 7, equipment data 1 consisting of equipment information 2, set information 3 and positional information 4 are transmitted from the local devices 1 to N to the computer system 9 via the remote monitoring device 7. The computer system 9 generates databases matching a format with a database generating means 94 based on the transmitted equipment data. The generated databases are written into an equipment database 8. Based on the equipment data written into the equipment database 8, display data editing and screen display processing means 92, 93 automatically renew and display the model illustration of the electric power system on the screen of the computer system.

摘要： PURPOSE: To perform the unitary management of a program by one machine and to enable remote maintenance for simultaneously distributing/exchanging programs by providing a means for matching the version of a common program and a means for maintaining consistency when partially exchanging the plural programs. CONSTITUTION: This system is provided with the means for matching the version of the common program to be simultaneously distributed to plural machines and the means for maintaining consistency when partially exchanging the plural programs having a common specification. Then, constitution information registered for each program is collected and the matching conditions of programs between machines are managed so that the computer constitution/program distribution/registration conditions inside a distributed system can be visually observed on a maintenance/management machine at a distant spot and the designated program can be distributed/registered by one action. When any mismatching is generated in the distribution conditions, it is enough for a program managing person only to instruct redistribution/re-registration to a software to display an alarm with one action.

摘要： PURPOSE:To eliminate necessity for caring of the competition of output requests from plural computers by generating physical control data corresponding to the specification of a printer with an image extending means and a physical data converting means. CONSTITUTION:Input data are received by a data reception part 111 and stored in a received data storage part 131, and the data are extended to a print image by a received data analysis/image extension part 112 and stored in a print image extended data storage part 132. Those data are converted to the physical control code of an output printer and character data by a printer physical data conversion part 113, further, the converted data are stored in a physical converted data storage part 133, and those data asre sent to the printer by a slip output control part 114. Thus, it is not necessary to care of the competition of output requests from plural computers.

摘要： PURPOSE:To automatically and easily execute a converting work by dividing case by case with use of characteristic information and converting and corresponding the result into the program sentence of a second language having the same function. CONSTITUTION:Concerning the program sentence to correspond by one-to-one, a conversion processing part 14 compares the contents of the said sentence storing part 12 and the contents of a grammatical expression correspondence table and converts it to the second language. On the other hand, concerning the sentence not to correspond, by using the characteristic information of the one, at least, either of a before- information temporary storing table 19 or an after-information temporary storing table 13, the correspondence is executed between the contents of the said sentence storing part 12 and the contents of the grammatical expression correspondence table and they are converted to the second language. Thus, when the program written in a low-class language is converted to a high-class language to be easily conserved, the conversion processing can be almost automatically executed even for a worker not to have a detailed knowledge concerning the contents of the program or the function.
