ICES' CONCEPTS AND FACILITIES

THE INTERGRATED CIVIL ENGINEERING SYSTEM /ICES/ IS DESIGNED FOR USE IN THE SOLUTION OF CIVIL ENGINEERING PROBLEMS. ICES DOES NOT PERFORM AUTOMATED ENGINEERING DESIGN, IT ASSISTS IN THE DESIGN PROCESS BY COORDINATING AND PROCESSING ALL RELEVANT PROBLEM INFORMATION. EXTERNALLY, ICES CAN BE VIEWED AS A SET OF ENGINEERING SUBSYSTEMS WHERE EACH SUBSYSTEM IS DESIGNED TO SOLVE PROBLEMS IN A PARTICULAR DISCIPLINE OF CIVIL ENGINEERING, SUCH AS STRUCTURAL ANALYSIS AND DESIGN, HIGHWAY ENGINEERING AND SOIL MECHANICS. INTERNALLY, EACH ICES SUBSYSTEM CONSISTS OF COMPUTER PROGRAMS THAT PERFORM ENGINEERING OPERATIONS ON ENGINEERING DATA. AN ENGINEERING PROGRAMING LANGUAGE, ICETRAN, IS USED TO WRITE THE SUBSYSTEM PROGRAMS. ICETRAN IS AN EXTENSION AND EXPANSION OF THE FORTRAN PROGRAMING LANGUAGE. THE ENGINEER COMMUNICATES HIS PROBLEM-SOLVING REQUESTS TO THE COMPUTER BY MEANS OF PROBLEM-ORIENTED LANGUAGE COMMANDS. THESE COMMANDS ARE PROCESSED BY THE ICES EXECUTIVE PROGRAM, WHICH USES INFORMATION ABOUT THE COMMAND STRUCTURE PROVIDED BY MEANS OF THE COMMAND-DEFINITION LANGUAGE. THE ENGINEERING OPERATIONS REQUESTED BY THE ENGINEER ARE PERFORMED BY ICETRAN BUILDING BLOCK ROUTINES WHICH HAVE BEEN PRECOMPILED AND COMPILED. DYNAMIC LINKING MECHANISMS ARE PROVIDED FOR COMMUNICATION BETWEEN ICETRAN PROGRAMS. THESE LINKAGES ENABLE PROGRAMS TO BE BROUGHT INTO PRIMARY MEMORY ONLY WHEN THEY ARE NEEDED. THE ICETRAN PROGRAMS PERFORM OPERATIONS ON ENGINEERING DATA THAT ARE STORED USING DYNAMIC DATA STRUCTURES. THESE DATA STRUCTURES ENABLE THE TYPE AND AMOUNT OF DATA ASSOCIATED WITH EACH PROBLEM TO BE HIGHLY VARIABLE. DYNAMIC MEMORY ALLOCATION ROUTINES ORGANIZE PROGRAMS AND DATA IN PRIMARY MEMORY, AND MEMORY REORGANIZATION PROGRAMS PURGE UNEEDED DATA TO SECONDARY STORAGE WHENEVER AVAILABLE SPACE IN PRIMARY MEMORY IS EXHAUSTED. AN ICETRAN PROGRAM MAY CREATE AND OPERATE UPON SECONDARY STORAGE DATA FILES USING THE ICES DATA MANAGEMENT CAPABILITIES. ICES OPERATES UNDER THE IBM OPERATING SYSTEM/360. /BPR/
