A customer who is willing to wait for some time until the company has restocked the products would have to place a backorder. A backorder only exists if customers are willing to wait for the order. In this paper, a neutrosophic inventory backorder problem using a triangular neutrosophic numbers is introduced. First, we fuzzify the carrying cost and shortage cost as triangular neutrosophic numbers and the signed distance method is used to defuzzify them. From these, we can obtain the neutrosophic optimal shortage quantity and the neutrosophic total cost. A numerical example is provided to illustrate the proposed model in neutrosophic environment.

Initially, the activity times<br> are static within the CPM technique and probabilistic within the PERT technique. Since neutrosophic set is the<br> generalization of fuzzy set and intuitionistic fuzzy set, a new method of project evaluation and review technique for a<br> project network in neutrosophic environment is proposed in this paper. Considering single valued neutrosophic<br> number as the time of each activity in the project network, neutrosophic expected task time, neutrosophic variance,<br> neutrosophic critical path and the neutrosophic total expected time for completing the project network are calculated<br> here.

After that, this concept has used in many areas like engineering, medical, commerce, economics, etc. Nowadays, the development of big cities with high quality of life is becoming a first challenge. Improving the existing transportation models more reliable and more sustainable towards smart mobility could contribute to achieve this aim. Today, whenever we are searching for a train which runs from a particular place to another place, either we get the names of trains between those two places or we will see that there is no direct train in that route. To avoid these situations, Fuzzy Dijkstra’s algorithm is applied to find the optimum routes among the places (stations). The aim of this paper is to give users with the information of all the trains from one station to another station with shortest route between them. Using this, users can easily findout the shortest routes between tw...

The purpose of this paper is to present demand as a neutrosophic random variable. For this model, a new method is developed for determining the optimal sequence size in the presence of neutrosophic random variables. Where to get optimality by gradually expressing the average value of integration. The newsvendor problem is used to describe the proposed model.

Pseudo SP-Ideal, identity pseudo SP-Algebra and characterization of their properties are defined and proved. Decomposition of any pseudo SP-Ideal of a pseudo SP-Algebra is also introduced in this paper.

For the five different initial metal ion concentrations such as 500, 600, 800, 900, 1000 mg/L, the steady-state values of chromium removal efficiency were 64, 92, 83, 71 and 66 %, respectively, using 5 grams of activated carbon under shaking at the end of 8th hour. The equilibrium of the process was found to fit into the two well-known adsorption models, Freundlich and Langmuir. It was also observed that the experimental kinetic data followed the first order rate expression.

In this paper, an algebraic structure known as "SP-RING", which is an extension of SP-Algebra has been introduced. The definition of SPRing , integral domain, some theorems, lemmas, properties and unique factorization theorem are also defined and discussed briefly.
