APPLICATION OF JOB SCHEDULING IN SMALL SCALE RICE MILLING FIRM

ABSTRACT Rice is the edible seed of a plant which is a member of the grass family. It is an annual plant which is grown in many countries throughout the world and is the staple diet for over half the world's population. Rice milling firm has therefore occupied a significant position in the small, medium and large scale enterprises of many nations. In application of job scheduling in rice milling activities a framework for proper scheduling of activities (jobs) in rice milling processing firm ...

Multi objective methods for welding flux performance optimisation

ABSTRACT The traditional welding flux development is by lengthy and costly trial and error experiments and the optimum welding flux formulation is not guaranteed. This paper presents discussions on promising multiobjective decision making (MODM) methods that can mitigate the limitations of the traditional approach to welding flux design. The methods are weighted-sum scalarization (WSS), desirability indices, goal programming and compromise programming. The steps a welding flux designer (WFD) ...

Application and Comparison of Three Multiobjective Linear Programming Methods

ABSTRACT A biobjective production planning problem was modelled using the Compromise Constraint Biobjective LP (CCBLP) method, the traditional Weighted-sum Scalarization (WSS) and Non-preemptive Goal Programming (NGP) approaches. Various preference indices were used to explore the tradeoff options and the ~ distance metric was used to determine the best compromise solution and the appropriate preference indices. The solution of CCBLP was the closest to the ideal solution with L1 metric of 0.3...

A BICRITERIA MODEL FOR PRODUCTION PLANNING IN A TOOTHPASTE FACTORY

ABSTRACT This paper presents a bicriteria formulation of the material allocation to production facilities problem. The system under consideration is a toothpaste factory. Two objectives of the factory were identified, namely; (i) Minimization of the total sum of processing costs (ii) Maximization of the capacity utilization of production facilities. Linear Combination of Objective Functions (LCOF) method was used to solve the problem for the situation where the objectives were of equal impor...

A NEURO-FUZZY LINGUISTIC APPROACH TO EXPERIMENTAL PARAMETERS 'WITH SILICON CARBIDE GRINDING WHEEL

ABSTRACT The paper presents a control system for grinding process using fuzzy rule-based model for estimating the grinding conditions at which wheel wears occur. The grinding parameters include circumferential speed of a grinding segment workpiece velocity and work depth of cut using silicon carbide grinding wheels. There was a wide range of applications over many types or mild steel materials and various wheel wear values were recorded for predicting the grinding conditions. Grinding wheels...

OPTIMIZING INVESTMENTS CASHFLOW A SCHEDULING APPROACH

ABSTRACT In this paper, the problem of optimising cash flow so as to enhance the financial feasibility of a multipart project is considered. The problem has been modelled as a single machine scheduling problem. Several sectors of the Nigerian economy where this problem is encountered are also discussed. A real life problem was solved on a PC using an electronic spreadsheet.

Local Sourcing of Raw Materials for the Manufacture of Manual Metal Arcwelding Electrode: A Case for Locally Produced Steelwire in Nigeria

ABSTRACT Since early 1995 when pressure was mounted on the Raw Materials Research and development council in Nigeria, with a  view to sourcing wire, flux and binder locally, little or no success has been recorded. As at 1998,allthe raw materials including core wire for electrode manufacture in Nigeria were still being imported. The aim of this project is therefore to explore the possibility of using locally sourced wire in electrode production. In this research, wire drawn at the Oshogbo rol...

APPLICATION OF NEUROFUZZY TO COMPONENT ELEMENTS OF A GRINDING WHEEL

ABSTRACT The grinding wheel is made up of very small, sharp and hard silicon carbide abrasive particles or grits held together by strong porous bond. These silicon carbide abrasive are hard crystalline materials which are held together by the strong, porous bond and these abrasive materials which are of extreme hardness are used to shape other materials by a grinding or abrading action. The paper presents, an analysis of the various component elements we have, the size of the grains and its s...

Development of low cost point of care device for detection of schistosoma Haematobium

Intestinal infections like worms are common in many poor countries and even when continuous  treatment is arranged at low cost, diagnostics and identification of treatment fails due to unavailability of diagnostic equipment and resources. With the proliferation of raspberry pi micro controller, data transfer networks and digital microscopy applications the stage is set for alternatives to conventional microscopy in endemic areas. Our aim was to show, as proof of concept, that it is possible ...

Application of fuzzy clustering data mining approach to garment sizing problem

ABSTRACTCurrently owing to the annual increase of data, there is urgent need for anthropometric database and useful approaches, in designing machine, equipment, facilities, workspace and other products. Fuzzy clustering which is an important way of clustering is an approach where an object is grouped into more than one partitions. The approach is used to bridge the gap between the anthropometry dimension of an individual and garment size which is a problem attributed to the size of the garmen...

Evaluation of The Effectiveness of Quality Control in Dangote Cement Plc

   v  ABSTRACT  The project evaluates the effectiveness of quality control  in Dangote Cement PLC, Ibese  Ogun  State,  Nigeria.  Limestone,  shale  and  laterite  samples  were  from  the  mines  to determine their right grade as well as their mixing proportion. Also samples were taken from kiln feed and the final stage of cement production. The compressive strength of the cubes is determined according to the ages of the cubes which is 2 days, 7 days and 28 days while the d...

Evaluation and assessment of relocation from a city to the outskirts: Case study DHL Gävle Sweden

Abstract The ‘City Logistics’ activities are contributing to traffic congestion and accumulating to environmental challenges, such situation has prompted the creation of urban consolidation centre (UCC), as a multimodal logistics park facility in the outskirts. The relocation of business from city to the outskirts requires the evaluation and assessment of the key factors in order to make the better decisions. However, no relocation decisions evaluation model has been found, neither its ap...

The role of informal Sector in employment generation in Ilorin, kwara state Nigeria

                       Abstract This research work examined the role of informal Sector in employment generation in  Ilorin, kwara state Nigeria. The study made use of primary data obtained from 100  respondents from Ilorin West Local Government in kwara state through the copies of  questionnaire administered. The data collected was analysed using descriptive statistics  and statistical package for social sciences (SPSS). The outcome of the empirical  investigations showed th...
