OBJECT-ORIENTED PARTS INVENTORY INFORMATION SYSTEM MODELING USING UNIFIED MODELING LANGUAGE

The availability of spare parts in a vehicle service workshop needs to be correctly recorded and recorded, making it easier for workshop owners to ensure the complete availability of vehicle spare parts. From the results of the author's observations, the Rizki Prima workshop has several obstacles in recording the availability of spare parts where the business processes being carried out are still a hassle for the employees working in the workshop. The problem often occurs when recording is the incompleteness of data related to incoming and outgoing goods. So the recording made in the ledger needs to be more accurate and requires a relatively long time to search one by one in the register if the workshop owner needs it. As a result of poor recording of goods, it is difficult for the owner to order goods again, worried that duplicating data will record incoming goods. The above problems are the basis for the authors to conduct research by utilizing information systems and modeling with an object-oriented approach using a unified modeling language to design a spare parts inventory information system according to user needs. To provide an overview of the Rizki Prima workshop transforming from conventional spare parts data recording to digital spare parts recording.

Implications of the 2022 Q2 Consumer Price Index (CPI) on Nigerian Consumers – Way Out

Abstract: Consumer Price Index (CPI) is a major indicator used to track inflation rate and cost of living in a country’s economy. Nigeria consumers have over the years been subjected to economic hardship amidst abundant natural resources. Today, cost of living is very high and commodity prices have become unaffordable to many Nigerian consumers. The financial hardship as a result of harsh economic policies, mismanagement of the citizen’s collective commonwealth, corruption, and embezzlement of public fund have created extreme inflation with many consumers unable to afford regular meals in a day. This paper examines the implications of 2022 Q2 Consumer Price Index on Nigeria consumers. It reveals that in the Q2 of 2022, prices of food increased beyond the purchasing power of the average Nigerian consumers. Motor vehicle fuel and natural gas prices increased year on year beyond the reach of the average Nigerian consumers. The cost of electricity, prices for new and used vehicles, motor vehicle spare parts and equipment and even inter and intra state transportation all increased exponentially. A cursory examination of the Q2 of 2022 CPI shows that the purchasing power of consumers declined and the high poverty and unemployment a\level hurts the poor disproportionately. The study suggested among others that government should pursue realistic economic and customs regulatory reforms, deregulate the sale of petroleum products, deregulate power generation and distribution, reduce the level of corruption and enshrine social safety net initiatives especially for the poor. The study concluded that Nigeria consumers are poorer in Q2 of 2022 compared with the same level in preceding years.

A comparative lexical analysis of vehicle spare parts terms in Arabic

PurposeInvestigating technical terms of vehicle spare parts used in the mechanics' jargon in Saudi Arabic (SA) and Yemeni Arabic (YA) has received scant attention. The current study, therefore, is an attempt to shed some light on the topic. The aim is to identify the strategies used for creating equivalents in vehicle spare parts vocabulary and to pinpoint the most salient variations between the two dialects in this jargon.Design/methodology/approachMore than 250 terms of vehicle spare parts were collected and analyzed qualitatively. Each list contains nearly 125 items. They were gathered from two main resources: semi-structured interviews with vehicle mechanics, and written lists from spare parts dealers in both countries.FindingsThree main strategies are found at work: lexical borrowing (from English and French), metaphor and loan translation. Direct borrowing is the most influential strategy where loanwords represent nearly one-third of the data, the majority of which is from English. Metaphorical extensions and literal translations also have an important role to play in the process of spare part naming. While the two dialects share common practices in terms of literal translation, they are characterized by many differences with regard to lexical borrowing and metaphors.Originality/valueThe study approaches an under-researched topic that is related to the mechanic's jargon in Arabic and leaves the door open for further research. The findings of this study may be used as guidelines for Arabic academies and those who are concerned with translating and studying technical terms in the field of mechanical engineering.

Kenya mandatory IPR recordal: an innovative measure with an uncertain future

Economic growth in Africa as well as its rising middle and upper class is a reality: household consumption in Africa has increased faster than the continent’s gross domestic product (GDP), which itself has consistently outpaced the global average. Consumer expenditure has been growing at a compound annual rate of 3.9 per cent since 2010, from US$1.4 trillion in 2015 to an expected US$2.5 trillion by 2030. It is therefore no wonder that brand owners are showing an increased interest in entering and solidifying their stakes in the African markets. One major issue faced by brand owners, however, is the wide availability of counterfeit and pirated goods in Africa. No product is spared, whether it be medicines, smartphones or copyrighted content such as music, film and software. According to World Health Organization statistics, 42 per cent of detected cases of substandard or falsified pharmaceuticals occur in Africa—this is more than on any other continent.1 A European Union Intellectual Property Office (EUIPO) study found that in Africa, 21.3 per cent of total sales of smartphones were lost in 2015 due to fake smartphones. This represents 7 million handsets with a total value of €1 billion.2 In Algeria, it is estimated that 60 per cent of creative content—in particular, music and film—are pirated copyright goods. Pirated software goes up to 84 per cent.3 This is only the tip of the iceberg: counterfeiting extends beyond these products and concerns industries as diverse as apparel, vehicle spare parts, electronics, household appliances, luxury goods and fast-moving consumer goods such as food products, toiletries and beverages.

Intermittent demand forecasting for spare parts in the heavy-duty vehicle industry: a support vector machine model

Intermittent demand occurs commonly for spare parts in the heavy-duty vehicle industry. Demand uncertainty and intermittency pose challenges to demand forecasting by conventional models. Support vector machine (SVM) models have been observed to yield competitive accuracy with existing models. However, there are still limitations for basic SVM models. First, the time-consuming computation does not bring a statistically significant accuracy improvement. Second, the forecasting-based inventory performance has not been sufficiently explored. Third, scarce explanations of model robustness are offered for demand forecasting. We build an adaptive univariate SVM (AUSVM) model to forecast intermittent demand. Its effectiveness, compared to 12 existing models and an improved neural-network, is demonstrated by real-world data from a heavy-duty vehicle spare-part company. AUSVM has an apparent advantage in computation time over basic SVM and neural networks. The computational results of the heavy-duty vehicle case indicate that, compared to well-known parametric models, AUSVM achieves a statistically significant accuracy improvement and better inventory performance for the group of non-smooth demand series. Discussions are presented on why AUSVM works for demand forecasting and inventory control of heavy-duty vehicle spare parts. Several insights are revealed for practitioners in the heavy-duty vehicle industry.
