The theory of the delivery chain considers the delivery of goods and services to customers within a specific time interval. Nowadays, organizations are focusing to satisfy their customers’ demands not only to meet the expectations for products quality but also in delivery times through managing delivery chains. Obviously it is desirable that a company has minimum delivery time of goods and services to its customers. Therefore, establishing economic and reliable control charts for monitoring the key characteristics of delivery chain is of great importance especially for managers to improve the whole delivery chains performance. On the other hand, as we shall see in the present paper, the performance of a delivery chain is multivariate in nature because customers do not evaluate a delivery performance with a univariate mindset and also there are usually several production and delivery sites, and variety of different methods of transportation of goods and services. In this paper, we propose a relatively new application of the economic statistical design of the multivariate T2 control chart to monitor the delivery chain performance and it is illustrated through a case study in the TNT express mail in Iran.

Delivery chains are concerned with the delivery of goods and services to customers within a specific time interval; this time constraint is added to the usual consumer demand for product or service quality. In this context, we address the idea of using process control tools to monitor this key variable of delivery time. In applications, there are usually several production and delivery sites and a variety of different ways to transport, treat and provide goods and services; that makes the problem multivariate in nature. We therefore propose to control the process using multivariate T2 control charts economically designed with the addition of statistical constraints, a design method called economic-statistical design. We illustrate the application in general through an illustrative example. [less ▲]

In this review paper, the authors critically analyse the use of a number of depth of anaesthesia monitors in light of the most recent literature and their own clinical experience. There appears to be increasing evidence that anaesthesia depth monitors reduce the incidence of unexpected intraoperative awareness and also that they improve the quality of anaesthesia. Proper use of these monitors necessitates background knowledge about the physiology of the loss of consciousness, the type of variable recorded and processed by the monitoring devices, the factors that might interfere with recording and the limits of use. The information provided by anaesthesia depth monitors is detailed and relationships with clinical practice are established to provide the reader with key features for optimal use of those monitors and correct interpretation of data. Practitioners and patient's knowledge and expectations regarding this matter, as well as the cost-benefit relationship are also discussed. [less ▲]

In February 1999, a poisoning episode broke out in several industrial poultry farms in Belgium. The source of this contamination was found to be a stock of recycled fat that had been delivered by a firm to several compound feed producers, between 19 and 31 January 1999. A very good correlation was observed between dioxins (PCDFs and PCDDs) and PCBs. Consequently a contamination mainly by PCBs was hypothesized. This finding made it possible to detect contaminated animals and animal products by dosage of the PCBs, more specifically by the 7 congeners with numbers 28, 52, 101, 118, 138, 153 and 180. The advantages of the dosage of PCBs compared to dioxins were its rapid test protocol and the fact that a larger number of laboratories could participate. In the cattle sector, 409 herds (0,81 p. cent) were submitted to the risk of feed contamination. The methodology used to detect a PCBs/dioxins contamination in the Belgian cattle population that was not submitted to the risk, is presented. This population is directly or indirectly destined for human consumption. It consisted in the systematic sampling of all calve fattening stations and all lots of exported bovines, and in the random sampling of slaughter cattle. This methodology is compared to the approach described in directive 96/23/CE. [less ▲]

La gestion des cours d’eau est un exercice difficile qui nécessite souvent de conjuguer différents objectifs et contraintes. Pour assurer une gestion de qualité soucieuse du respect de la multifonctionnalité de ces milieux, il apparaît primordial de disposer d’un état des lieux des ressources à un moment donné et surtout de leur évolution au cours du temps de celles-ci. Le monitoring des bandes riveraines doit donc être considéré comme un outil d’aide à la gestion, à la disposition tant des gestionnaires que des décideurs politiques. [less ▲]

For climatic stress detection and monitoring in the Heilongjiang Province, north-eastem China, an indicator on the interannual vegetation state was extracted from the AVHRR Pathfinder image set (1981-2000) and compared to the rainfall variations over the growing season (June to August). The results show that the vegetation status does not closely depend on rainfall variations in this region. Temperatures, which showed a rapid augmentation in the northern high latitudes since the early 1980s, seem to be a more crucial limiting factor for vegetation growth. Rapid land cover change and large natural disasters are also likely to impact the relationship between rainfall and vegetation. [less ▲]

Wallonia (Southern Region of Belgium) has implemented the Nitrates Directive by designating four vulnerable zones (now 42% of the territory) and introducing a first Action programme at the start of November 2002 and a second one in 2007. The Action programmes entail various means of reducing the risks of the pollution of water by nitrate: (a) struggle against nitrate losses in fields using a range of good agricultural practices, including certain restrictions on the use of fertilisers (quantities, spreading periods, soil conditions, etc.), (b) keeping a balance on each farm between the organic nitrogen produced and spreading capacities on agricultural land, (c) adapting storehouses for livestock effluent to a capacity of 6 months and (d) promoting transfers of livestock effluent between farms in excess balance and farms which still have a way of using it on their land. The paper presents the principle of “soil nitrate residue” measurements (APL in French) that permits a yearly monitoring of the farming practices and constitutes a self-evaluation tool for the farmers. The paper also introduces the reference model EPICgrid dedicated to nitrogen transfer modelling in the context of the Walloon region. Following the first comparison exercise, these tools are consistent and complementary approaches to help farmers and authorities in nitrogen management. In the context of the Walloon region, dealing with deep groundwater bodies, fast indicators of potentially leachable nitrogen and nutrient fate modelling are the most practical way of assessing effectiveness of the EU nitrate directive action programmes.

The monitoring of two controlled landfills in Tunisia was carried out for about 10 years by CITET and CWBI. Both landfills were managed by classical methodology i.e. disposal, compaction and, if any, biogas and leachate extraction and treatment. One of them is located near Tunis and the other near Sousse with a warmer climate. They received more than 6,000 and 350 thousand cubic metre of MSW respectively from the two cities. Solid samples were collected by boring at different depths up to 18 m. They were analysed for dry weight and for total organic carbon, nitrogen and (hemi-) cellulose. The boreholes were equipped with 200 mm perforated PEHD tubes for further biogas and leachate sampling and analyses (COD, VFA, CH4 content, …) at different seasons. The results indicate an efficient mesophilic anaerobic digestion in both landfills. The high dry weight content (70 – 92%) of 13 solid samples collected in Sousse landfill contrasts however with the high leachate production in the Tunis landfill, filling about completely the majority of boreholes. The results of this monitoring confirm the trends formerly described about biological activity and environmental impact of landfills in Tunisia. Moreover a 200 L pilot-scale anaerobic digester was operated for about 3 years with solid wastes from Tunis landfill to assess the evolution of moisture content and organic matter. [less ▲]

Measuring performances of health professionals and health facilities is a difficult task. However, with the appropriate information management tools, a lot of useful information can be collected from routine data registration activities. Situated in the capital of Rwanda, the Central Kigali University Teaching Hospital developed in January 2006 its electronic patient record using both ICD10 and ICPC2 codes for the structured registration of diseases and procedures. In order to enable synoptic data analysis, individual codes have been grouped into a set of 174 disease groups (KHIRI Pathology Group Set –KPGS). To assess the activities and performances of the different clinical departments, outcome data were analyzed following a number of essential criteria: the caseload, the LOS (length of stay) load and the in-hospital mortality load. A total number of 27784 patients were admitted during the study period. On the 27784 patients a total of respectively 30609 and 29447 diagnoses were recorded in ICPC2 and ICD10. The total of hospitalization days was 395256. 2759 patients died over the 3 years study period. Four ICPC classes covered more than 10% of the encodings each: A (general) 5649, D (digestive system) 6040, L (locomotors system) 3297 and R (respiratory system) counted for 4026 registrations. Comparable results could be obtained in the corresponding ICD classes A+B, K, M+S-T and J. Linking ICD10 and ICPC2 codes to global patient data clearly enables the physicians and the hospital management to produce comparable, standardized and internationally valuable evaluations of the hospital activities and trends. It also opens the perspective of fixing objective priorities in patient management and provides an interesting starting point for comparing health professionals’ clinical performances in a standardized way.
