Modeling and Practical Solution Algorithm for Improving the Operation Efficiency of Pre-cut Lumber Warehouse

By: Takashi Tanizaki , Masahide Arino , Takayuki Kataoka

Page No : 1-18

Abstract
Pre-cut lumber is a wooden building material that is cut to the size of pillars, beams, and other building elements and fitted with joint brackets as necessary. In Japan, the use of pre-cut lumber as a building material for wooden houses is increasing due to its advantages such as shorter construction time and lower construction costs. The demand for pre-cut lumber is increasing, but the number of pre-cut lumber production plants is decreasing, thus improving the production efficiency of pre-cut lumber is an issue. Based on the above background, we have been working to improve the productivity of a pre-cut production process. As part of this project, we are studying how to improve the operational efficiency of a pre-cut lumber warehouse. In this paper, the scheduling algorithm for production processes and warehouses that produces products in an easy-to-pack sequence to reduce the number of packing racks in the warehouse is proposed.

Characterization of Some New Matrix Classes over Ultrametric Fields

By: P N Natarajan

Page No : 19-26

Abstract
In this paper, K denotes a complete, non-trivially valued, ultrametric (or nonarchimedean) field.  Entries of sequences, infinite series and infinite matrices are in K. The purpose of this paper is to characterize the matrix classes ( ) , mc lm  and  ( ) 0, mc lmin terms of the entries of an infinite matrix in these classes.

Some Studies in Ultrametric Analysis

By: P N Natarajan , Edward Beckenstein

Page No : 27-36

Abstract
In this paper, K denotes a non-trivially valued, ultrametric (or non-archimedean) field. Entries of sequences and infinite series are in K. In the first section, we introduce the preliminaries that are required in the sequel. In the second section, we prove some results which are special in ultrametric analysis. In section 3, we prove some interesting results about Cauchy sequences in K. In the final section, we give some examples of ultrametrics and ultrametric spaces.

A Graphical Approach to Horadam Sequences with Periodic Coefficients

By: R. Patrick Vernon , Gurdial Arora , Sindhu Unnithan

Page No : 37-44

Abstract
It has been shown by the authors [10] that a linear recurrence relation with periodic coefficients can sometimes be split into relations with constant coefficients. In this paper, we present a graph-theoretic approach to show that all such second-order relations can be split into second-order relations with constant coefficients, and give a new method for calculating these coefficients.

A New Solution Methodology for Matrix Games with Multiple Experts in Interval-Valued q -Rung Orthopair Fuzzy Environment

By: Deeba R. Naqvi , Rajkumar Verma , Geeta Sachdev

Page No : 45-77

Abstract
In practical decision-making scenarios, involving groups, such as communities, assemblies, or committees, is common. These groups collaborate to achieve collective goals, but reaching a consensus can be intricate due to conflicting information presented by various members. The complexity introduced by divergent viewpoints makes it challenging to ascertain the optimal outcome within a group decision-making framework. In response to these challenges, this paper introduces an innovative methodology for addressing two-player zero-sum matrix games with payoffs represented by Interval-Valued q-Rung Orthopair Fuzzy numbers, taking into account the insights provided by multiple experts. To navigate the intricacies of this class of matrix games, the paper proposes an aggregation approach designed to fuse the diverse payoff matrices contributed by the experts. This aggregated matrix then serves as the foundation for establishing a two-player zero-sum Interval-Valued q-Rung Orthopair Fuzzy (IVq-ROF) matrix game. This matrix game framework is instrumental in determining optimal strategies for the players involved, offering a practical solution to the complexities introduced by multiple experts and conflicting information. The proposed methodology is further elucidated through a numerical example, effectively illustrating its application in real-world scenarios. The paper conducts validity tests and a comparative investigation, highlighting the advantages of the suggested approach over existing methods, particularly in addressing the challenges of complex competitive scenarios in the real world. Overall, this innovative solution methodology stands as apromising contribution to enhancing group decision-making processes, offering a robust framework to handle conflicting information and derive optimal outcomes in challenging real-world contexts.
