dynamic cellular manufacturing systems,   mixed-integer non-linear programming,   production planning, manufacturing attributes   this paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (dcms) based on production planning (pp) decisions and several manufacturing attributes. such an integrated dcms model with an extensive c...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

in order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. in this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. also because of t...

production planning is performed through diverse methods according to the type of the system it is structured upon. one of the most important steps before production planning is to determine which system best fits the firm, and how the facilities should be designed. both job-shop and group-technology systems have their own pros and cons, each of which is suitable to a specific kind of factory. ...

This paper analyzes preemptive patenting in a two-stage real options game where an incumbent firm competes with a potential entrant firm for the patent of a substitute product in a product market with profit flow uncertainty. The incumbent suffers loss of monopoly in the product market if the entrant acquires the patent of a substitute product and later commercializes the product. Our patent-in...

The mechanism of action of diphenylhydantoin (DPH) on re-entrant ventricular arrhythmias (RVA) was studied in dogs 3-7 days following ligation of the anterior descending coronary artery utilizing direct recordings of the re-entrant pathway (RP) from the epicardial surface of the infarction zone (IZ). DPH in a therapeutic dose consistently prolonged refractoriness of potentially RP in the IZ. Th...
