Coordination and Compensation Model of E-Commerce Dual-Channel Supply Chain Based on Optimized Genetic Algorithm

Due to the conflict between traditional channels and electronic channels in the e-commerce dual-channel supply chain, retailers are threatened and need to be compensated in some way. Based on this, an e-commerce dual-channel supply chain coordination compensation model based on optimized genetic algorithm is designed. Based on the problem description and basic assumptions, analyze the manufacturer’s profit and the retailer’s maximum profit in the case of centralized decision-making and decentralized decision-making. The genetic algorithm is optimized by introducing a collaborative genetic operator, and the optimized genetic algorithm is used to obtain dual e-commerce channels. The maximum profit of the supply chain, so far, the model design is completed. Through comparative experiments, the optimized genetic algorithm used in the model is compared with two traditional algorithms. Experimental results show that the proposed algorithm takes shorter iteration time to solve the problem, its convergence is better, and it can effectively obtain a global optimal solution instead of a local optimal solution.

Multivariate Markov Chain Model for Sales Demand Estimation in a Company

Estimation of the number of demands for a product must be done correctly, so that the company can get maximum profit. Therefore, this study discusses how to estimate the amount of sales demand in a company correctly. The model that will be used to estimate sales demand is the Multivariate Markov Chain Model. This model can estimate the future state by observing the present state. The model requires parameter estimation values ​​first, namely the transition probability matrix and the weighted Markov chain, where in previous studies an estimation of the transition probability matrix has been carried out, so that in this study we will continue to estimate the weighted Markov chain parameters. This model is compatible with 5 data sequences (product types) defined as product 1, product 2, product 3, product 4, and product 5, with 6 conditions (no sales volume, very slow-moving, slow-moving, standard, fast moving, and very fast moving). As the result, the state probability for product 1, product 2 and product 3 in company 1 are stationary at state 6 (very fast moving), product 4 and product 5 are stationary at state 2 (very slow moving).

Finally, numerical simulation is used to verify the model and put forward a method of coordination for all parties in the tourism supply chain to achieve maximum profit.

Analysis of Bus Fare Structure to Observe Modal Shift, Operator Profit, and Land-Use Choices through Combined Unified Transport Model

In order to design sustainable urban transport systems, the inclusion of the behaviors of different stakeholders is imperative. In this study, we formulated the interactions of behaviors between transport operator, landowner, workplace, residence, route and mode choices, and location of firms and businesses through a combined unified model of land-use and transport system. The commuters have two mode choices for traveling: private car and public bus. They are inclined to choose a transit mode with minimum traveling costs. We combined two models, maximization of operator profit constrained by bus frequency, while maintaining the formulation of other stakeholders through an assignment sub-model. The resulting formulation is bi-level, which is optimally solved for a small-sized instance containing two zones. The findings suggest that if the bus fare is reduced, the demand of public bus is increased. However, the operators’ profit is optimized within a certain range of fares and is lowered when the fare is too low or too high. It is determined that maximum bus frequency does not guarantee maximum profit to the service operator. The impacts of traveling costs on residence choice behavior suggest that if link fares are more, many of people opt not to travel between different zones. The analysis results presented in this paper are calculated for two types of link fares: a fixed fare (30 currency), and a range of link fare (5 to 100 currency). Different variants of the same formulation can be applied for real settings to better comprehend the nature of the model and its applications.

JUAL BELI VALUTA ASING DALAM PERSPEKTIF HUKUM ISLAM

ABSTRAKKejadian baru-baru ini yang melanda bangsa Indonesia mengenai krisis ekonomi telah banyak menyengsarakan kehidupan rakyat khususnya dalam bidang pangan. Kejadian krisis tersebut selain dilanda wabah covid-19 juga diakibatkan dengan salah satunya adalah adanya transaksi jual beli valas di bursa valas yang disalahgunakan oleh para spekulan. Mereka hanya bertujuan untuk mencari keuntungan yang sebesar-besarnya (menjadikan uang dan sebagai alat tukar menjadi alat komoditi) tanpa melihat kehidupan bangsa Indonesia di masa yang akan datang. Hal ini tentunya muncul berbagai permasalahan, di antaranya: 1) Bagaimana pelaksanaan transaksi kurs beli dan kurs jual valuta asing, dan 2) Bagaimana alasan ketetapan jual beli valuta asing menurut hukum Islam. Tujuan dari penelitian ini adalah: 1) untuk mengetahui pelaksanaan transaksi kurs beli dan kurs jual valuta asing, dan 2) untuk mengetahui alasan ketetapan jual beli valuta asing menurut hukum Islam. Berdasarkan hasil pengkajian dan penelitian terhadap literatur-literatur yang relevan dengan permasalahan ditemukan bahwa dalam Islam dikenal berbagai transaksi jual beli baik yang dilarang maupun yang dibolehkan. Terdapat tiga bagian dalam transaksi valas, yaitu: transaksi spot, transaksi forward, dan transaksi swap. Dari ketiga transaksi tersebut berdasarkan pengkajian terhadap literatur yang dibolehkan menurut hukum Islam adalah transaksi spot atau dalam istilah hukum Islam yadan biyadin (tunai). Sedangkan transaksi forward dan transaksi swap hukumnya haram, karena transaksi tersebut di dalamnya mengandung unsur riba.ABSTRACTThe recent events that hit the Indonesian people regarding the economic crisis have made many people's lives miserable, especially in the food sector. Apart from being hit by the COVID-19 outbreak, this crisis was also caused by one of which was the existence of foreign exchange buying and selling transactions on the forex market that were misused by speculators. They only aim to seek the maximum profit (making money and as a medium of exchange into a commodity) without looking at the life of the Indonesian people in the future. Of course, various problems arise, including: 1) How to carry out transactions of buying and selling foreign exchange rates, and 2) What are the reasons for the determination of buying and selling foreign exchange according to Islamic law. The objectives of this study are: 1) to determine the implementation of the transaction of buying and selling foreign exchange rates, and 2) to find out the reasons for the determination of buying and selling foreign exchange according to Islamic law. Based on the results of studies and research on the literature relevant to the problem, it was found that in Islam there are various buying and selling transactions, both prohibited and permitted. There are three parts to foreign exchange transactions, namely: spot transactions, forward transactions, and swap transactions. Of the three transactions, based on a review of the literature, what is permitted under Islamic law is a spot transaction or in terms of Islamic law yadan biyadin (cash). Meanwhile, forward transactions and swap transactions are illegitimate, because these transactions contain elements of usury.
