Our research focuses on the development of two cooperative approaches for resolution of the multi-item capacitated lot-sizing problems with time windows and setup times (MICLSP-TW-ST). In this paper we combine variable neighborhood search and accurate mixed integer programming (VNS-MIP) to solve MICLSP-TW-ST. It concerns so a particularly important and difficult problem in production planning. ...

The 2013 educational plan was formed into an program that consolidates different viewpoints, in particular mentalities, information, and abilities. Through the plan, teachers are needed to have option work on nature of instruction order deliver autonomous innovative understudies. Coordinated science learning is introduced with regards which incorporates climate, innovation, society. Science (sc...

In this paper, we propose a new neighborhood semantics for contingency logic, by introducing a simple property in standard neighborhood models. This simplifies the neighborhood semantics given in Fan and van Ditmarsch [4], but does not change the set of valid formulas. Under this perspective, among various notions of bisimulation and respective Hennessy-Milner Theorems, we show that c-bisimulat...

Following the idea of $L$-fuzzy neighborhood system as introduced byFu-Gui Shi, and its generalization to $(L,M)$-fuzzy neighborhood system, the relationship between  $(L,M)$-fuzzy topology and $(L,M)$-fuzzy neighborhood system will be further studied. As an application of the obtained results, we will describe the initial structures of $(L,M)$-fuzzy neighborhood subspaces and $(L,M)$-fuzzy top...

In subsequent papers I propose to investigate various properties of fibre spaces. The object of the fundamental Hurewicz-Steenrod definition is to state a minimum set of readily verifiable conditions under which the covering homotopy theorem holds. An apparent defect of their definition is that it is not topologically invariant. In fact, for topological space X and metrizable non-compact space ...

We describe an example of a C°° diffeomorphism on a 7-manifold which has a compact invariant set such that uncountably many of its connected components are pseudocircles. (Any 7-manifold will suffice.) Furthermore, any diffeomorphism which is sufficiently close (in the C1 metric) to the constructed map has a similar invariant set, and the dynamics of the map on the invariant set are chaotic. Co...
