Sensitivity analysis of a railway station track layout with respect to a given timetable
Article Abstract:
A study was conducted to develop an algorithm for the sensitivity evaluation of a railway station track layout based on a given timetable. The algorithm supported the simulation of a Markov chain with a state space that is a subset of the set of feasible timetables. A set of integer variables and binary relations were analyzed to generate random solutions. Results indicated that the algorithm effectively carried out a sensitivity analysis on a given timeframe.

Single machine scheduling problem with fuzzy precedence relation
Article Abstract:
The single machine scheduling problem with fuzzy precedence relation is studied by means of nondominated schedule vectors and a solution algorithm. The problem is analyzed with regard to two objectives, namely, the maximum lateness to be minimized and the minimal satisfaction level with respect to fuzzy precedence relation to be maximized. Results indicate that the proposed algorithm is very useful for solving single machine scheduling problems.

Some new efficient methods to solve the n/1/r(i)/epsilon T(i) scheduling problem
Article Abstract:
New methods for solving the n/q/r(i)/epsilon T(i) or one-machine scheduling were derived when an adequate condition for local optimality was established. Newdominant subset of schedules and several approximate algorithms were defined based on this condition. Numerical experimentation enabled a comparison of these new algorithms with the classical approximate algorithms. An optimal solution is therefore possible in a smaller solution space.
