The multi-level production problem is one of the challenging research areas in supply chain management. We present brief literature review and mathematical models of multi-level just-in-time sequencing problem with a view of cross-docking approach for supply chain logistics. Describing cross-docking operations, we propose a mathematical model for the cross-docking supply chain logistics problem to minimize the operation time as truck sequencing problem. We establish a proposition as the synthesis of the production and logistics.Key Words: Just-in-time; Supply chain; Logistics; Cross-dock; Operation timeDOI: http://dx.doi.org/10.3126/jie.v8i1-2.5114Journal of the Institute of Engineering Vol. 8, No. 1&2, 2010/2011Page: 219-230Uploaded Date: 20 July, 2011

The multi-level just-in-time sequencing problem is one of the challenging research areas in supply chain management. In this paper, we present brief review and some recent research developments of just-in-time production systems together with supply chain logistics. Observing production flows and supply chain synchronization in production process, we present the mathematical models of just-in-time (JIT) sequencing problem in multi-level and single-level as nonlinear integer programming in terms of discrepancy functions under the specified constraints. Discrete apportionment approach is briefly reported as an efficient frontier for single-level.  Journal of the Institute of Engineering, 2015, 11(1): 91-100

 Synchronization of all partners along a supply chain logistics system is one of the challenges in most of the business operations. In this paper, we present a brief literature review of cross-docking approaches for supply chain logistics problem. On describing the problem, we formulate the supply chain logistics problem as a truck sequencing problem to minimize the discrepancies of operation times of inbound and outbound trucks. The problem is decomposed in two sub-problems as inbound and outbound parts as a solution strategy.Journal of Institute of Science and Technology, 2014, 19(1): 39-44

The aim of the article is to answer the question of whether the implementation of the requirements of the ISO 22000 standard in the food supply chain can support the implementation of key processes occurring in them, and thus increase the level of food quality and minimize its waste. The research was conducted out among several European countries, and an attempt was carried out to compare how the standard is perceived by entrepreneurs operating in Poland, Slovakia (Central and Eastern Europe), and Portugal (Western Europe). Covering the Polish, Slovak, and Portuguese organizations with the research process resulted from the fact that in recent years in these countries, an increase in the diversity of food demand and fragmentation of the food market has been observed. This forced food supply chains to be strictly focused on increasing the efficiency and effectiveness of production and distribution systems, as well as taking into account customer requirements and the implementation of sustainable solutions. Based on the results of the research, it can be concluded that the implementation of the requirements of the ISO 22000 standard along food supply chains can positively affect the implementation of key processes and thus contribute to reducing food waste at each stage of the supply chain.

Abstract Purpose To review the seafood dietary recommendations of European countries and compare them to national seafood supplies. Methods Current seafood dietary recommendations were collated from national health authorities across Europe. Food balance sheets were downloaded from the FAO, and appropriate conversion factors were applied to each seafood commodity. Average net per capita seafood supplies from 2007 to 2017 were derived from data on imports and production for food from both capture fisheries and aquaculture, accounting for exports. Results Both national dietary recommendations and seafood supplies varied considerably throughout Europe. At a national level, on a per capita basis, only 13 out of the 31 of European dietary recommendations for fish consumption were satisfied by national seafood supplies. Most of the countries with coastal access, as well as those with traditional fish-eating cultures, such as France and countries in Northern Europe, had adequate seafood supplies to meet their recommendations. The landlocked countries of Central and Eastern Europe did not have enough seafood supplies to satisfy their recommendations. Conclusions Our findings emphasise the need to not only consider consumer health outcomes when developing and advocating dietary recommendations, but also the sustainability of food production systems. As many foods are not necessarily locally sourced but traded as part of global production and distribution systems, it is important to consider greater consistency between national dietary recommendations to facilitate more sustainable marine food systems.

The Cost

In this study, an inter-continental agricultural pellet supply chain is modeled, and the production cost and price of agricultural pellets are estimated and compared against the recent cost and price of wood pellets in the global marketplace. The inter-continental supply chain is verified and validated using an integration of an interactive mapping application and a simulation platform. The integrated model is applied to a case study in which agricultural pellets are produced in six locations in Canada and shipped and discharged at the three major ports in Western Europe. The cost of agricultural pellets in the six locations is estimated to be in the range of EUR 92–95/tonne (CAD 138–142/tonne), which is comparable with the recent cost of wood pellets produced in small-scale pellet plants (EUR 99–109/tonne). The average agricultural pellet price shipped from the six plants to the three ports in Western Europe is estimated to be in a range of EUR 183–204 (CAD 274–305/tonne), 29–42% more expensive that the average recent price of wood pellets (EUR 143/tonne) at the same ports. There are several potential areas in the agricultural pellet supply chains that can reduce the pellet production and distribution costs in the mid and long terms, making them affordable supplement to the existing wood pellet markets. Potential economic activities generated by the production of pellets in farm communities can be significant. The generated annual revenue in the biomass logistics system in all six locations is estimated to be about CAD 21.80 million. In addition, the logistics equipment fleet needs 176 local operators with a potential annual income of CAD 2.18 million.

AbstractThis article presents the results of the zooarchaeological analysis of an assemblage dating to the second quarter of the 16th century that was discovered on the current university campus of Cartuja, on the outskirts of Granada (Andalusia, Spain). During the Middle Ages, this area was largely used for agricultural purposes, including as estates owned by high officials of the Nasrid dynasty, the last Islamicate polity in the Iberian Peninsula. The Castilian conquest of Granada in 1492 brought significant changes to the area, with the construction of a Carthusian monastery and the transformation of the surrounding landscape, including changes in property structures, different agrarian regimes and the demolition of pre-existing structures. Among these transformations was the filling up of a well with construction materials, and its further use as a rubbish dump. This fill yielded an interesting and unique zooarchaeological assemblage, the study of which is presented here. The results advance our understanding of changing patterns in animal consumption during the formative transition from the Middle Ages to the Early Modern period at the heart of the former Nasrid Kingdom of Granada, and indicate the continuity of some Andalusi consumption patterns along with specialised production and distribution systems of meat products that have no archaeological precedent in the region, suggesting that the bones were dumped by a possible ‘Morisco’ community (autochthonous Muslims forced to convert to Christianity in 1502).

Multi-level cell (MLC) phase change memory (PCM) can not only effectively multiply the memory capacity while maintaining the cell area, but also has infinite potential in the application of the artificial neural network. The write and verify scheme is usually adopted to reduce the impact of device-to-device variability at the expense of a greater operation time and more power consumption. This paper proposes a novel write operation for multi-level cell phase change memory: Programmable ramp-down current pulses are utilized to program the RESET initialized memory cells to the expected resistance levels. In addition, a fully differential read circuit with an optional reference current source is employed to complete the readout operation. Eventually, a 2-bit/cell phase change memory chip is presented with a more efficient write operation of a single current pulse and a read access time of 65 ns. Some experiments are implemented to demonstrate the resistance distribution and the drift.
