In anticipation of price hikes and shortages caused by supplier disruptions manufacturer production stops, customers might stockpile extra products. the case a disruption, may decide to continue producing using contingent source. Capturing dynamics in four disruption-related periods (i.e., responding, rising, recovering, recovered), we derive optimal hoarding policies for customers. The results indicate that customer decisions fall into multiple patterns depending on interactions between...
Recently we have modified our collisionless, time‐dependent, kinetic plasma model (Wilson et al., 1990) to include the effects of Coulomb self‐collisions in a theoretically rigorous fashion. The algorithm employed (Takizuka and Abe, 1977) faithfully mimics Fokker‐Planck operator conserves both energy momentum. This collisional has been applied problem baseline plasmasphere refilling an initially depleted flux tube, neglecting wave‐particle interactions. companion report by Lin al. (this...
We study the dynamic behaviour of a hybrid system where manufacturing and remanufacturing operations occur simultaneously to produce same serviceable inventory for order fulfilment. Such system, commonly found in photocopier personal computer industries, has received considerable attention literature. However, its performance resulting bullwhip effect, under push pull policies, remain unexplored. Relevant analysis would allow considering adoption appropriate control strategies, as some...
The effective operations of closed-loop supply chains (CLSCs) can help companies achieve sustainability goals and boost economic performance. In practice, CLSCs must collect used products, a complex process that is often constrained by collection station capacity. However, how capacity influences the bullwhip effect dynamic performance remains unclear. Here, we develop system dynamics model for integrates traditional manufacturing with remanufacturing explore effects stochastic constraint on...
Carbon fibre-reinforced plastic (CFRP) composites, prized for their exceptional properties, often encounter surface quality issues during slotting due to inherent heterogeneity. This paper tackles CFRP challenges by employing multi-tooth mills in experiments with various fibre orientations and tool feed rates. In-plane scratching tests are performed under linearly varying loads; then, conducted at different parameters. The test results indicate that the orientation cutting angles have...
This paper investigates the system dynamics of a hybrid manufacturing and remanufacturing operating under first-order autoregressive (AR(1)) demand governed by lost-sales rules. Lost sales occur when customers, after encountering stock-out, are unwilling to delay their purchases. is particularly relevant in industries like groceries, clothing, cell phones, where customers more sensitive stock-outs compared backlog systems. Given presence autocorrelated AR(1) these industries, study focuses...
The combined make-to-stock and make-to-order (MTS-MTO) supply chain is well-recognised in the semiconductor industry order to find a competitive balance between agility, including customer responsiveness minimum reasonable inventory, achieve cost efficiency while maintaining service levels. Such hybrid MTS-MTO may suffer from bullwhip effect, but few researchers have attempted understand dynamic properties of such system. We utilise model Intel analytically explore underlying mechanisms...
ABSTRACTWith the significant growth of e-commerce business, retail industry is experiencing rapid developments, leading to explosion number stock-keeping units (SKUs). Therefore, it calls for forecasting algorithms forecast a large product-level demands over short horizon. We developed novel machine learning algorithm—the spatial-temporal gradient boosting tree (ST-GBT)—for demand industry. By incorporating cross-section and time-series information in existing gradient-boosting decision...
We treat the early stages of plasmasphere refilling along an initially depleted L =4 magnetic flux tube through a semikinetic model. The companion paper by Wilson et al. (this issue) describes plasma evolution for “baseline” situation in which Coulomb collisions play central role. Here we focus on effects wave‐particle interactions stochastic diffusion ions perpendicular velocity due to equatorially concentrated electromagnetic ion cyclotron waves plays examine characteristic individual...
The hybrid assembly-to-order (ATO) supply chain, combining make-to-stock and make-to-order (MTS-MTO) production, separated by a customer order decoupling point (CODP), is well recognised in many sectors. Based on the well-established Inventory Order Production Control Systems (the IOBPCS family), we develop ATO system dynamics model analytically study impact of nonlinearities its dynamic performance. Nonlinearities play an important, sometimes even dominant, role influencing performance...
We have extended our previous semikinetic study of early stage plasmasphere refilling with perpendicular ion heating (Lin et al., 1992) by removing the restriction that northern and southern boundaries are identical incorporating a generalized transport description for electrons (e.g., Brown 1991). This allows investigation effects electron more realistic calculation electric fields produced temperature anisotropies. The combination parallel leads to an equatorial electrostatic potential...

Purpose This paper aims to explore blockchain integration strategies within a three-level livestock meat supply chain in which consumers have preference for quality trust products. The investigates three questions: First, how does consumers’ affect and transaction decisions among participants? Second, under what circumstances will retailers choose participate the blockchain? Finally, can other factors such as costs supplier–retailer partnership value decisions? Design/methodology/approach...
