A hybrid FJA-ALNS algorithm for solving the multi-compartment vehicle routing problem with a heterogeneous fleet of vehicles for the fuel delivery problem
Authors: Chowmali Wasana , Sukto Seekharin
Published: August 2021

This paper proposes a new hybrid algorithm to solve the multi-compartment vehicle routing problem (MCVRP) with a heterogeneous fleet of vehicles for the fuel delivery problem of a previous study of twenty petrol stations in northeastern Thailand. The proposed heuristic is called the Fisher and Jaikumar Algorithm with Adaptive Large Neighborhood Search (FJA-ALNS algorithm). The objective of this case is to minimize the total distance, while using a minimum number of multi-compartment vehicles. In the first phase, we used the FJA to solve the MCVRP for the fuel delivery problem. The results from solving the FJA were utilized to be the initial solutions in the second phase. In the second phase, a hybrid algorithm, namely the FJA-ALNS algorithm, has been developed to improve the initial solutions of the individual FJA. The results from the FJA-ALNS algorithm are compared with the exact method (LINGO software), individual FJA and individual ALNS. For small-sized problems (N=5), the results of the proposed FJA-ALNS and all methods provided no different results from the global optimal solution, but the proposed FJA-ALNS algorithm required less computational time. For larger-sized problems, LINGO software could not find the optimal solution within the limited period of computational time, while the FJA-ALNS algorithm provided better results with much less computational time. In solving the four numerical examples using the FJA-ALNS algorithm, the result shows that the proposed FJA-ALNS algorithm is effective for solving the MCVRP in this case. Undoubtedly, future work can apply the proposed FJA-ALNS algorithm to other practical cases and other variants of the VRP in real-world situations.

Published: August 2021

Investments in the agricultural sector represented by innovations and new technologies strongly influence the economic growth in developing countries. In this context, purchasing decisions have become more relevant. Multiple-criteria decision-making techniques are well suited for decision-makers (DMs) who are considering the introduction of new technologies. In this paper, a multi-criteria model is built to help a Colombian agricultural research company make decisions on purchasing different laboratory equipment. A compensatory approach based on trade-offs is used to elicit the preferences of a group of DMs. The high number of answers and cognitive effort required from them during the elicitation process led to using an alternative approach based on partial information, called the FITradeoff (The Flexible and Interactive Tradeoff) method. It showed to be the best fit to solve the company’s purchasing problem and allowed its managers to make decisions that consider criteria other than price, taking account of the DMs’ conflicting viewpoints. The proposed model aimed at contributing to the articulation of the end-user knowledge in decision-making in order to ensure effective articulation of actors and strengthening of science, technology and innovation in agriculture.

Published: August 2021

Among the various routes of drug delivery, the oral route is an attractive site for the delivery of drugs. The main advantages of these formulations are: drug targeting, sustained release, increased permanence time in the buccal mucosa, increased bioavailability, and decreased potential adverse effects and maintains constant blood levels for extended period of time. The buccal cavity was found to be the most suitable and easily accessible site for the delivery of therapeutic agents for both local and systemic delivery. Buccal mucosa has a tremendous availability, which leads to direct access to systemic circulation through the internal jugular vein bypasses the drug from hepatic first pass metabolism. The main disadvantage of this route is Limited absorption area- the total surface area of the membranes of the oral cavity available for drug absorption is 170 cm2 of which ~50 cm2 represents non-keratinized tissues, including buccal membrane, the barrier function of the skin changes from one site to the other and from one person to other person with age and large dose of drug are difficult to be administered. Melt granulation is emerging technique and this technique used to increase the dissolution rate of poorly water-soluble drugs. Tablet molding technique: Tablets produced by the molding technique are easier to scale up for industrial manufacture than lyophilisation technique. Hot melt extrusion of film method: Hot melt extrusion has been used for the manufacture of controlled release matrix tablets, pellets and granules, as well as oral disintegrating films.

Com a crescente demanda por Geração Distribuída (GD), em especial a Fotovoltaica (GDFV), o planejamento do sistema elétrico de distribuição considerando a participação da GDFV é essencial. Assim, torna-se necessário a aplicação de metodologias de simulação que melhor representem a inserção de GDFV no sistema elétrica. Este trabalho realiza a simulação de três possíveis percentuais de GDFV (10%, 20% e 30%) a serem inseridos em um sistema de 33 barras. As simulações são realizadas de três perspectivas: considerando a inserção em todas as barras; alocação pseudoaleatória; e alocação aleatória. Nas simulações são observados os níveis de tensão e perda ativa. A escolha inadequada da metodologia a ser utilizada nas simulações com GDFV pode comprometer os estudos realizados.

Published: August 2021

O conversor híbrido impedância série tem como característica a associação de duas tecnologias, a dos conversores chaveados e amplificadores lineares. A associação proposta, é em série, ou seja, o conversor chaveado e o amplificador linear estão em série com a carga. O amplificador linear é implementado com um transistor sem fonte de alimentação própria, desta forma a estrutura é classificada como conversor de impedância série, devido a forma de atuação do amplificador linear que simula uma impedância variável que se modula para a eliminação da ondulação de saída. A metodologia de projeto do conversor proposto leva em conta a perda máxima admissível sobre o amplificador linear. Esta metodologia é validada através de simulações e experimentações práticas.

Objective: Acute Appendicitis encounters as the frequent problem in surgical pediatric patients leading to Appendectomy, being one of the most common procedures performed in surgical Emergency. During COVID-19 pandemic, the trends in the management of acute appendicitis have changed. Conservative management of appendicitis with antibiotics is being proposed as an alternative to conventional appendectomy. So, this study is conducted to compare the presentation and outcome of Appendicitis managed during pre and post pandemic period in our settings. Methodology: After approval of Ethical Review Committee, a total of 267 patients of age 1-12 years were selected for the study. It was a retrospective Cohort Study. Patients were divided into group A (n=145) which was pre pandemic group. Data was collected retrospectively from charts regarding demographics, presentation, duration of stay operative findings and complications from May-Oct 2019 and Group B (n=122) during covid-19 was collected from the patients presented with appendicitis over a period of six months from May-Oct 2020 . Similar months of the year were selected to remove seasonal variation in the presentation of Appendicitis. All information was collected on a predesigned Performa. Data was compared and analyzed on SPSS 20. Results: Out of 267 patients, 151 (56.56%) were male. Group A patients presented during pre-pandemic period (n=145) were undergone appendectomy for appendicitis in 129 patients (88.96%) with 59 patients (40.68%) having acutely inflamed appendix and 70 patients (48.27%) had complicated appendicitis such as gangrenous, perforated with generalized peritonitis. In Group A only 16 patients (11.03%) were managed conservatively for appendicular mass. In contrast to group B (n=122) presented during pandemic, only 43 patients (35.24%) were operated with findings of acutely inflamed appendicitis while gangrenous/perforated appendicitis with pelvic abscess and/or generalized peritonitis was found in most of the patients with a number of 69 (56.55%), only 10 (8.19%) patient presented as Appendicular mass hence managed conservatively. Conclusion: Delay in presentation and early conservative management during pandemic crisis has resulted in an increase in the complications of Appendicitis. Early referral to specialized centers with vigilant selection for conservative treatment can save patients from developing complications.

La stérilisation est essentielle dans la prévention des infections nosocomiales et pour la sécurité des patients. Cette étude a pour objectif d'évaluer le respect des normes du processus de stérilisation des dispositifs médicaux et textiles opératoires dans hôpitaux du Mali et du Sénégal, en Afrique de l'ouest. Il s'agissait d'une étude prospective descriptive réalisée sur une période de quatre mois. Les données ont été recueillies par entretien avec les surveillants des unités de stérilisation centrale et par observation directe des pratiques de stérilisation. Elles  ont été saisies et analysées avec le logiciel Epi info3.3.2. Des produits de nettoyage et de désinfection conformes aux normes en vigueur étaient disponibles dans 3 des 7 hôpitaux enquêtés. L'usage d'un emballage secondaire était pratiqué dans 2 hôpitaux au Sénégal. Au Mali, la moitié des hôpitaux stérilisait leurs dispositifs métalliques à la vapeur d'eau tandis qu'au Sénégal tous les hôpitaux le faisaient. Les unités de stérilisation évaluées dans les deux pays n'avaient pas encore mis en place un système d'assurance qualité. Dans 6 des hôpitaux, la place du pharmacien en unité de stérilisation était occultée et le personnel n'avait pas bénéficié de formation selon les bonnes pratiques de Stérilisation.  Les insuffisances relevées ont permis de formuler des recommandations pour une meilleure pratique de la stérilisation et partant, l'amélioration de la qualité des soins dans les deux pays.Mots clés : Stérilisation, Dispositif médical, Textile opératoire, Hôpital, Mali, Sénégal

Indonesia tersusun di atas empat lempeng tektonik besar yaitu Lempeng Eurasia, Lempeng Australia, Lempeng Pasifik, dan Lempeng Filipina. Lempeng-lempeng tektonik tersebut saling bergerak secara aktif dan dinamis sehingga mengakibatkan terjadinya deformasi pada kerak bumi. Deformasi menyebabkan terjadinya perubahan bentuk, posisi, maupun dimensi pada objek-objek di atas permukaan tanah, termasuk objek-objek pengukuran dan pemetaan yang dilakukan oleh Kementerian ATR/BPN. Penelitian ini dilakukan untuk mengkaji perubahan yang terjadi pada objek-objek pengukuran dan pemetaan (data administrasi pertanahan) akibat adanya deformasi pada kerak bumi. Data pertanahan yang digunakan dalam penelitian ini berbentuk data grid dan data hasil pengukuran di lapangan. Data pertanahan tersebut kemudian dimodelkan perubahannya akibat adanya deformasi. Model deformasi yang digunakan dalam penelitian ini adalah model deformasi yang dibuat oleh Badan Informasi Geospasial (BIG). Selain itu, digunakan pula model potensi gempa bumi di selatan jawa untuk menghitung pergeseran teoritis akibat deformasi koseismik. Hasil dari penelitian ini menunjukkan bahwa deformasi yang terjadi selama 14 tahun mengakibatkan pergerakan sejauh 40 cm. Selain model linear yang diakomodasi oleh model deformasi yang dibuat oleh BIG, pergerakan tiba-tiba akibat gempa bumi juga berpotensi mengakibatkan pergerakan yang bersifat lokal maupun regional. Tentunya pergerakan ini secara eksplisit berdampak kepada perubahan posisi data pertanahan. Perubahan posisi tersebut berpotensi mengakibatkan terjadinya perubahan luas maupun terjadinya overlap dan gap yang akan menjadi permasalahan tersendiri pada kegiatan pemetaan di BPN.
