After that, we must decide whether precedence relation we put in is correct.
Proposition 1 The precedence relation is irreflexive, antisymmetric, and transitive.
A precedence relation (shortly, a precedence) can be considered as a couple ([f.sub.1], [f.sub.2]) where [f.sub.1] = rnd(nrphases) [f.sub.2] = rnd (nrphases) and [f.sub.1] [not equal to] [f.sub.2] .
[PI] is satisfying disassembly precedence relations between n components of all the feasible set of permutations, and n = {[[pi].sub.1], [[pi].sub.2], ..., [[pi].sub.[absolute value of [PI]]}
The Simple Assembly Line Balancing (SALB) Problem aims to assign a set of tasks to a set of workstations such that: A) Each task is assigned to only one workstation B) Precedence relations among the tasks are not violated and C) One or more objectives are optimized.
His skillful braiding of these two lines of inquiry yields a nuanced description of how political processes flowing from the center have refashioned authority schemata that developed on the periphery, and projected them into newly created social domains (schools, bureaucracies, unions, parties)--establishing a predominance of stylized "precedence relations" that are neither traditional nor modern.
