Abstract:
Determining efficient solutions for large scale transportation problems is an important task in operations research. In this study, Vogel’s Approximation Method (VAM) which is one of well-known transportation methods in the literature was investigated to obtain more efficient initial solutions. A variant of VAM was proposed by using total opportunity cost and regarding alternative allocation costs. Computational experiments were carried out to evaluate VAM and improved version of VAM (IVAM). It was seen that IVAM conspicuously obtains more efficient initial solutions for large scale transportation problems. Performance of IVAM over VAM was discussed in terms of iteration numbers and CPU times required to reach the optimal solutions.

Abstract:
This paper presents a variant of Vogel's approximation method (VAM) for transportation problems. The importance of determining efficient solutions for large sized transportation problems is borne out by many practical problems in industries, the military, etc. With this motivation, a few variants of VAM incorporating the total opportunity cost (TOC) concept were investigated to obtain fast and efficient solutions. Computational experiments were carried out to evaluate these variants of VAM. The quality of solutions indicates that the basic version of the VAM coupled with total opportunity cost (called the VAM–TOC) yields a very efficient initial solution. In these experiments, on an average, about 20% of the time the VAM–TOC approach yielded the optimal solution and about 80% of the time it yielded a solution very close to optimal (0.5% loss of optimality). The CPU time required for the problem instances tested was very small (on an average, less than 10 s on a 200 MHz Pentium machine with 64 MB RAM).

Abstract:
This research was conducted at UKM Jovelyn in Batam city. Jovelyn's UKM produces various kinds of cakes and is marketed in markets in Batam City. The UKM opened 4 branches and marketed its products to 7 markets in the city of Batam. Product distribution is still random and not properly regulated. This resulted in a very large transportation cost, up to 1/3 of the total production cost. This shows that product transportation is still not carried out effectively and efficiently. The transportation problem is converted into a mathematical form so that the problem can be solved by the transportation method. The transportation method aims to minimize the objective function which is a function of transportation costs. The transportation method is basically the same as the linear program where at each iteration a selection is made to enter the basic variabel and leave the basic variabel. There are several iteration methods, namely the northwest corner method, minimum cost method, genetic algorithm, Vogel's approximation method, minimum row method, Russell's approximation method and column minimum method. Previous research has shown that the Vogel's approximation method, and Russell's approximation method are more efficient and accurate. This study uses both methods and a sensitivity analysis is performed to optimize the calculation results. The sensitivity analysis aims to determine the extent to which the objective function constants and the constraint function constants can change Keywords: Transportation, Sensitivity, SME

Abstract:
Transportation problems (TP) are one of the most prominent fields of application of the mathematical disciplines to optimization and operations research. In general, there are three starting basic feasible solution methods: Northwest Corner, Least Cost Method, VAM – Vogel's Approximation Method. The three methods differ in the quality of the starting basic solution. In this study, we actually show a new method for starting basic feasible solution to one‐criterion‐transportation problems: Çakmak Method. This method can be used for balanced or unbalanced one-criterion transportation problems, and gives the basic feasible optimum solution accordingly.

Abstract:
A well-organized arithmetical procedure entitled standard deviation is employed to find the optimum solution in this paper. This technique has been divided into two parts. The first methodology deals with constructing the entire contingency cost table, and the second deals with optimum allocation. In this work, the method of magnitude is used for converting fuzzy numbers into crisp numbers as this method is better than the existing methods. This technique gives a better optimal solution than other methods. A numerical example for the new method is explained, and the authors compared their method with existing methods such as north west corner method, least cost method, and Vogel's approximation method.

In this paper, we will solve the four index fully fuzzy transportation problem (\textit{FFTP$_{4}$}) with some adapted classical methods. All problem's data will be presented as fuzzy numbers. In order to defuzificate these data, we will use the ranking function procedure. Our method to solve the \textit{FFTP$_{4}$} composed of two phases; in the first one, we will use an adaptation of well-known algorithms to find an initial feasible solution, which are the least cost, Russell's approximation and Vogel's approximation methods. In the second phase, we will test the optimality of the initial solution, if it is not optimal, we will improve it. A numerical analysis of the proposed methods is performed by solving different examples of different sizes; it is determined that they are stable, robust, and efficient. A proper comparative study between the adapted methods identifies the suitable method for solving \textit{FFTP$_{4}$}.

Abstract:
This research aims to determine the tofu product distribution transportation model at Taufik Tofu Factory. This type of research is applied research with a quantitative approach. The method used to solve transportation problems in this study is the Modified Vogel’s Approximation Method (MVAM) and optimized using the Modified Distribution (MODI) method. The results of this study indicate that the application of MVAM at the Taufik Tofu Factory provides a more minimum solution for calculating transportation costs, both in equilibrium and non-equilibrium problems. MVAM provides the same transportation costs as the optimal solution for the simplex method, which is equal to Rp1.164.911,00 for equilibrium problems and Rp2.176.838,00 for unequal problems. These results have been tested for optimism using MODI and better than the real cost calculations issued by the factory.

Abstract:
In the distribution process, a large number of transportation costs are required because the costs incurred are unstable and also depend on field and weather conditions. In addition, the road conditions in Medan are getting congested, so that traffic jams have to be dealt with by the delivery party. Therefore a strategy is needed to minimize costs so that problems do not arise in distributing products to various regions. The information system that will be built to help resolve cases that occur in service providers, especially at the JNE Medan Main Branch, uses a method known as a method of transportation. Vogel's Approximation Methods (VAM) is a transportation method used to regulate the distribution from sources that provide the same product to places where it is optimally needed.

Abstract:
The transportation cost of goods in any company or organization is a pivotal element in determining the total cost of production and also the net profit that will be made. The main aim of this study is to minimize the cost of transporting goods produced at Grand Cereals Limited, Jos, which is reducing the cost of transportation from the major plant where the goods are produced to the various distribution centers. Data was collected on the average quantity of Brabusco Maize Flour (10 kg), Grand Pure Soya Oil (10 litres), Vita Chicks Pelletized Feeds (25 kg, 9 mm) and Royal Layer Concentrate Feeds (25 kg) produced monthly at the Jos plant, the average quantity demanded by major distributors across the country (Yola, Dutse, Minna, Abuja, Aba, Onitsha, Calabar and Ikeja) and the cost of transporting them. The Vogel's Approximation Method of the TORA Optimization System Software was used in solving the formulated transportation problem, and an optimal solution of N3,427,821.00 was obtained, which reduced the monthly transportation cost by N332,179.00. Furthermore, sensitivity analysis was carried out on the parameters after the optimal solution was obtained, which shows that the optimal solution is strongly sensitive to changes in the problem parameters. It was concluded that this work has reduced the transportation cost of the company and therefore recommended to the management of the company for adoption in planning their transportation schedule at a minimum cost.

This paper presents modified Vogel’s method that solves the fixed charge transportation problems, the relaxed transportation problem proposed by Balinski in 1961 to find an approximate solution for the fixed charge transportation problem (FCTP). This approximate solution is considered as a lower limit for the optimal solution of FCTP. This paper developed the modified Vogel’s method to find an approximate solution used as a lower limit for the FCTP. This is better than Balinski’s method in 1961. My approach relies on applying Vogel’s approximation method to the relaxed transportation problem. In addition, an illustrative numerical example is used to prove my hypothesis.

Abstract:
Purpose: Transportation problem plays an important role in operations research. The more generalized cases of transportation problems are trans-shipment problems. Further, the trans-shipment problems may have a set of trans-shipment nodes, or the source/destination nodes themselves act as the trans-shipment nodes. The study of the trans-shipment problems and their solution methodology is the goal of this paper. Methodology: The solution of a trans-shipment problem could be done by transferring it to a transportation problem. Further, there exist various conventional methods for solving the transportation problem. The present paper discusses about the scope of application of an existing heuristic algorithm directly over the trans-shipment problem. The heuristic is based on the minimum spanning tree approach. We implement the algorithm over a test problem and further compare its performance by the performance of the corresponding algorithm Vogel’s Approximation Method. Main findings: The spanning tree approach gives a better solution or almost the nearby solution as compared to the solution obtained by Vogel’s Approximation Method. Implications: The solution obtained by the spanning-tree approach takes lesser computational effort to reach a better feasible solution. The novelty of study: The algorithm to deal with the trans-shipment problem i.e. for finding the feasible solution of the trans-shipment problem is the main focus of this paper.Transportation Problem

The distribution of fertilizers in Central Sulawesi Province has not been efficient due to the large transportation costs in March 2016, the distribution of fertilizers could not go directly to retailers because the distance between regencies was far enough so that fertilizer was sent to distributors before to retailers to minimize costs to be incurred. company. Transhipment problems are in the form of indirect distribution problems because the products sent must go through several stages before reaching the consumer. This study will compare the Vogel Approximation method in previous studies with the completion of linear programming with Lingo software tools. Transportation costs using the Vogel Approximation method in previous studies compared with transportation costs using the Lingo software tool have the same cost of IDR 508,289,000, but there are several different fertilizer distributions. Lingo software simplifies data processing so that the results obtained are more accurate than the Vogel Approximation method. Companies can use lingo software to minimize costs by working effectively and efficiently.

No-wait flow shop scheduling is a type of manufacturing scheduling which finds applications in advanced manufacturing systems and falls under the category of NP-hard combinatorial optimization problem. Heuristic methods are found to be the most suitable ones for obtaining solutions to these problems. We propose a heuristic method based on Vogel’s Approximation Method for developing the solution for the objective of minimizing total flow time in no-wait flow shop. The computational results are compared with the results of the well known existing heuristics in no-wait flow shop for minimizing the total flow time criterion. The results reveal that the proposed method significantly outperforms the existing heuristics, with comparable computational time. Statistical tests are used to validate the performance of the proposed method.

Abstract:
Transportation problem (TP) in operations research is a widely used optimization technique to study the problems concerned with transporting goods from production places to sale points. The TP may have one or more objectives such as minimization of transportation cost, minimization of distance with respect to time, and so on. There is a systematic method to solve such problems. For this, we find the Initial Basic Feasible Solution (IBFS) to the given problem. North West corner method, least cost method, Vogel’s approximation method are the standard methods one uses to find the IBFS. In recent years, there are several other methods are proposed to solve such problems. In this paper, we propose a new technique named as Direct Sum Method (DSM) and its effectiveness is compared with the standard methods. The result shows that it is easy to compute and near to the optimum solution of the problem.

Abstract:
Metode transportasi adalah metode yang digunakan untuk mengatur distribusi dari sumber-sumber yang menyediakan produk yang sama ke tempat-tempat yang membutuhkan secara optimal. Alokasi produk ini harus diatur sedemikian rupa, karena terdapat perbedaan biaya-biaya alokasi dari satu sumber ke suatu tempat tujuan. Kasus transportasi timbul ketika suatu perusahaan mencoba menentukan cara pengiriman (distribusi) suatu jenis barang (item) dari beberapa sumber (lokasi penawaran) ke beberapa tujuan (lokasi permintaan) yang dapat meminimalkan biaya. PT. X dihadapkan pada pemasalahan semakin tingginya biaya pemasaran karena tidak teraturnya pola pendistribusian dari tempat sumber ke tempat tujuan pemasaran, sehingga perusahaan berusaha untuk mengoptimalkan biaya transportasi yang dikeluarkan. Hal ini, jika di biarkan dapat mengakibatkan kerugian bagi perusahaan. Metode analisa data yang digunakan untuk memecahkan masalah tersebut menggunakan metode transportasi, untuk solusi awal menggunakan metode pojok kiri atas pojok kanan bawah (North West Corner Method), ongkos terkecil (Least Cost Method), VAM (Vogel’s Approximation Method) dan uji optimal menggunakan metode batu loncatan (Stepping Stone Method) dan MODI (Modified Distribution). Pendistribusian produk pakan ternak di PT. X dengan menggunakan metode transportasi didapatkan hasil yang optimal. Total biaya transportasi untuk solusi awal menggunakan metode pojok kiri atas pojok kanan bawah (North West Corner Method) = Rp. 43.118.639.196,-; ongkos terkecil (Least Cost Method) = Rp. 43.094.262.979,-; VAM (Vogel’s Approximation Method) = Rp. 43.089.578.434,- dan uji optimal menggunakan metode batu loncatan (Stepping Stone Method) dan MODI (Modified Distribution) didapatkan hasil yang optimal adalah : Rp. 43.087.656.564,-.

Abstract:
Detailed calculations for bound muon capture in complex nuclei are performed by employing the quasi particle random phase approximation (QRPA). The required bound muon wavefunctions for the large and the small components of the Dirac muon wavefunctions are obtained by using the genetic algorithm approach. We ob- tained contributions for 2p muon orbit; that is to say wavefunctions for atomic ex- cited state of the muonic atoms in nucleus 28Si. As a byproduct the above method give the corresponding energies to these wavefunctions which are compared with those of other methods. Our goal is to use the method developed recently by Laganke, Zinner and Vogel and our advantageous numerical approach to obtain state by state calculations of the muon capture rates within the QRPA.

Abstract:
For twenty decades, there is a visible ever forward advancement in the technology of mobility, vehicles and transportation system in general. However, there is no "cure-all" remedy ideal enough to solve all life problems but mathematics has proven that if the problem can be determined, it is most likely solvable. New methods and applications will keep coming to making sure that life problems will be solved faster and easier. This study is to adopt a mathematical transportation problem in the Coca-Cola company aiming to help the logistics department manager of the Asejire and Ikeja plant to decide on how to distribute demand by the customers and at the same time, minimize the cost of transportation. Here, different algorithms are used and compared to generate an optimal solution, namely; North West Corner Method (NWC), Least Cost Method (LCM) and Vogel’s Approximation Method (VAM). The transportation model type in this work is the Linear Programming as the problems are represented in tables and results are compared with the result obtained on Maple 18 software. The study shows various ways in which the initial basic feasible solutions to the problem can be obtained where the best method that saves the highest percentage of transportation cost with for this problem is the NWC. The NWC produces the optimal transportation cost which is 517,040 units.

Abstract:
<p>Cost optimization approach of operational research is a predictive power and economy of compactness that is applied to solve specific clinical needs relevant to healthcare cost reduction. Technology helps the healthcare management, decision making, and policy that we have implemented in the interest of improving quality of patient care and treatment outcomes, thereby reducing costs and improving efficiency. The treatment cost of brain tumor is high. Sometimes, cost becomes a problem for individuals to get their complete treatment, which makes their health at risk and may lead to higher cost in future. Here we address neuroinformatics approach to optimize diagnosis cost in neurology through an operational research tool (optimization) on how the diagnosis cost of neuro-patient can optimize. In this context, we introduce a new and unique optimization approach in healthcare, yet what we are clearly lacking for applying applications of operational tools to translate this understanding to the different level to apply the concept in healthcare. The costs of treatment achieved by three standard initial basic feasible solutions (IBFS) methods (North-west corner method, Minimum cost method, Vogel’s approximation method) are 763, 763, and 779. The optimal solution is 761, and three random tests (RT’s) are 826, 783, and 788. Optimal solution provided an overall difference in treatment cost with IBFS 2, 2, 18 and with RT’s 65, 22, and 27. These results establish the basis for a deliberate integration of operational research tools and neuroscience into diagnosis of cost optimization mechanisms for neuro- patient.</p>

Abstract:
Ascertaining an optimal cement distribution plan for cement companies in Nigeria has remained a challenge. The absence or fluctuation of data for estimating the cost of transporting cement from each source to each distribution center is a big stumbling block whenever modeling attempts are being made via transportation algorithms. This work has succeeded in removing these challenges by providing a Transportation Optimization Model for cement distribution using transportation Distance Matrix instead of transportation Cost Matrix. This research seeks to improve supply in the Nigerian cement industry. Three selected factories (Gboko, Port-Harcourt and Calabar) and four major distribution centers (Abakaliki, Onueke, Ohaozara and Afikpo) in Ebonyi state were considered for this work. The result of the findings using the Vogel Approximation Method, minimized the total transportation distance and by implication the total transportation costs.

Neste artigo são apresentados quatro métodos heurísticos construtivos (denominados LPT, TOTAL, SCT e LPST) para programação da produção em sistemas flow shop híbridos com tempos de setup independentes da sequência de execução das tarefas. O foco deste trabalho é o estudo da influência da programação do primeiro estágio neste ambiente de produção. O critério de desempenho utilizado é a minimização da duração total da programação (makespan). O método LPT baseia-se na conhecida regra Longest Processing Time e sequencia as tarefas pela ordem crescente da soma dos tempos de processamento de todos os estágios. O TOTAL utiliza a ideia do Método de Aproximação de Vogel, considerando a matriz composta pela soma dos tempos de processamento e setup de todos os estágios. A denominação SCT foi atribuída a este método por escolher o par tarefa-máquina que conduz à menor data de término (Shortest Completion Time). E o método LPST atribui à máquina de menor carga a tarefa com a maior soma dos tempos de processamento e setup do primeiro estágio. Os resultados da experimentação computacional mostraram que o método SCT foi claramente superior aos demais, com 55,3% de sucesso, enquanto o LPT obteve 26,9%, o TOTAL atingiu 16,4% e por último o LPST apresentou 2,2% de sucesso. Palavras-chave: programação da produção; flow shop híbrido; setup independente. ABSTRACT This paper addresses the hybrid flow shop scheduling problem with sequence-independent setup times. Four constructive heuristic methods (called LPT, TOTAL, SCT and LPST) were proposed with objective to evaluate the influence of the schedule of the first production stage in this environment. The minimization of the total time to complete the schedule (makespan) was used as performance criterion. The LPT method is based on the well-known Longest Processing Time rule and it sequence the jobs by the ascending order of the total processing times of all stages. The TOTAL method uses the idea of Vogel Approximation Method, considering the matrix composed by the sum of processing and setup times of all stages. The SCT method chooses the pair machine-job that leads the Shortest Completion Time. And the LPST method designates to the lower load machine the job with the largest sum of processing and setup times of the first stage. Results of computational experiments reveled that the SCT method was clearly the superior, with 55.3% of success, while LPT obtained 26.9%, TOTAL reached 16.4% and lastly LPST presented 2.2% of success.

Abstract:
The paper is related with the basic transportation problem (TP)which is one kind of linear programming problem (LPP). There are some existing methods for solving transportation problem and in this paper all the standard existing methods has been discussed to understand which one is the best method among them. Among all of existing methods, the Vogel’s Approximation Method (VAM) is considered the best method which gives the better optimal result then other methods and North-West Corner Rule is considered as simplest but gives worst result. A C programming code for Vogel’s Approximation Method have been added in the appendix.

Abstract:
AbstrakPenelitian ini mengkaji hasil model transshipment dari proses pendistribusian barang di PT Sentosa Plastik Medan dengan menggunakan program WinQSB. Selain itu, model transshipment proses pendistribusian barang oleh perusahaan dibandingkan dengan model transshipment yang dihasilkan oleh program Solver.Metode yang digunakan dalam penelitian ini adalah metode dokumentasi, metode wawancara, dan studi pustaka. Data dalam penelitian ini diperoleh dari perusahaan. Adapun uraian dari metode-metode transshipment adalah sebagai berikut: (1) Metode untuk menyusun tabel awal antara lain Metode Sudut Barat Laut atau North West Corner Method (NWC), Metode Biaya Terkecil atau Least Cost Method, Vogell’s Aproximation Method atau VAM. (2) Model pegujian optimalitas algoritma transportasi antara lain Stepping Stone Method; dan Modified Distribution Method atau MODI. Berdasarkan hasil penelitian diperoleh bahwa selisih biaya pendistribusian untuk seluruh produk kain mori dengan menggunakan program WinQSB adalah sebesar Rp. 22.561.250,- lebih kecil dibandingkan hasil perhitungan perusahaan sebesar Rp.35.488.750,- Ini berarti terdapat selisih antara biaya pendistribusian yang menggunakan program WinQSB dengan biaya pendistribusian yang dilakukan oleh perusahaan yaitu sebesar Rp 12.927.500,-. Jadi biaya pendistribusian masih dapat diminimalkan sebesar 36,4%. Akan tetapi, sebelum melakukan tindakan lanjutan. Perusahaan juga perlu mempertimbangkan mengenai aspek dilapangan untuk meminimalkan biaya pendistribusian yang adaKata Kunci: Biaya Pendistribusian, Optimalisasi, WinQSB, dan Transshipment, Vogel Approximation Method (VAM)ABSTRACTThis study examines the results of the model transshipment of goods distribution process in PT Sentosa Plastic Medan using WinQSB program. In addition, the process of distributing goods transshipment models by the company compared to the transshipment models produced by the Solver program. The method used in this research is the method of documentation, interviews, and literature. Data in this study were obtained from the company. The description of the methods of transshipment is as follows: (1) A method for preparing the initial table among other methods Northwest Angle or North West Corner Method (NWC), or Least Least Cost Method Cost Method, Vogell's aproximation Method or VAM. (2) Model test of optimality transport algorithms include Stepping Stone Method; and Modified Distribution Method or MODI. The research showed that the difference in the cost of distribution for all products cloth using WinQSB program is Rp. 22.56125 , - lower than the calculation results of the company for Rp.35.488.750, - This means that there is a difference between the cost of distribution that uses WinQSB program at a cost of distribution conducted by the company in the amount of Rp. 12.9275 -. So the cost of distribution can still be minimized by 36.4%. However, before making any further action. Companies also need to consider the aspect of the field to minimize the cost of existing distribution.

Abstract:
This paper deals with the optimal approximate solution to a special type of optimization problem called a fuzzy transportation problem using pentagonal fuzzy numbers. The values of the cost, supply, and demand for fuzzy transportation problems are taken as pentagonal fuzzy numbers. The pentagonal fuzzy numbers are converted into crisp values using a novel suggested ranking function. By comparing this with the conventional ranking methods, we can achieve better results with the aid of the proposed new ranking method. Vogel’s Approximation Method is then applied to obtain the solution. Several experiments have been conducted in order to investigate the suggested technique.
