<P>PROBLEM TO BE SOLVED: To lighten the burden of scheduling operation for planning the processing order of a product by flexibly analyzing restriction conditions. <P>SOLUTION: In an operation restriction check device 1, a rolling restriction master 151 in a storage part 15 contains restriction conditions including restriction contents represented with a relation between a restriction content item using an operator corresponding to the restriction contents and a value of the restriction content item or combinations of the relations, and a restriction range in which the restriction contents are applied. A syntax analytical processing part 171 performs syntax analytic processing on the restriction contents contained as the restriction conditions to be checked in the rolling restriction master 151 to generate a syntax tree. A restriction condition determination processing part 173 determines whether a cycle or rolled material within the restriction range meets the restriction contents by using the syntax tree to determine whether the object to be checked meets the restriction conditions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
