SYNOPTIC ABSTRACTThis article presents an economic order quantity (EOQ), model for items with three-parameter Weibull distribution deterioration and quadratic demand trend. The model is developed and analyzed under quasipartial backlogging, i.e., in

We have developed a new method of solving geometric programming problems with as many positive degrees of difficulties as possible. Geometric programming has no direct solution whenever its degrees of difficulties are greater than zero; this has hind

In this paper, we develop an economic order quantity inventory model for items with three-parameter Weibull distribution deterioration and ramp-type demand. Shortages are allowed in the inventory system and are completely backlogged. The demand rate

The concept of stereographic projection from a circle to one of its tangent lines is applied in obtaining an F-distribution with degrees of freedom 1 and 3. The derivation brings out clearly the relationship between circular and non-circular distribu

In this paper a stochastic method is applied in the study of the long time effect of confinement in a correctional institution on the behaviour of a person with criminal tendencies. The approach used is Markov chain, which uses past history to predic
