Decision model for closed loop supply chain with uncertain demand and price-dependent returns

A single product closed-loop supply chain that satisfies an uncertain market demand with original and remanufactured products is considered.The yield of the recovery process is random and depends on the acquisition price offered for the end-of-life products.In such a stochastic setting,a firm needs to make production and procurement decisions so that the total expected profit is maximized.Both centralized and decentralized models are established depending on the party collecting the returns.The optimal acquisition price and production quantities of original and remanufactured products are determined for the firm.The contracts to coordinate the decentralized systems are chosen and the optimal contract parameters are determined.A computational experiment is given to show the effects of recovery parameters on the system performance.Results show that the recovery parameters have a high impact on the profitability of the manufacturer in the centralized model and on that of the collection agency in the decentralized model.

Analysis on the Several Nutrient Elements Demanded for the Growth of Wolffia globosa

[Objective] This study was to analyze the several nutrient elements de- manded for the growth of Wolffia globosa with the aim to provide references for the improvement on the formula of nutrient solution for the cultivation of Wolffia globosa. [Method] The basic conditions of the pond were simulated in the greenhouse, and nutrient solution was added to cultivate Wolffia globosa. The main element composi- tions of the experimental water, wild water and dried Wolffia globosa were detected by inductively coupled plasma spectrometer （ICP） and element analyzer, in order to study the nutrient demand for Wolffia globosa growth. And the absorption of N, P, K and consumption of P for the growth of Wolffia globosa were also analyzed. [Re- suit] The Wolffia globosa biomass of the experimental group which cultivated by adding nutrient solution increased over time, and after 2 weeks, the average capacity was significantly more than initial capacity; and the average capacity of the control group without nutrient solution was significantly lower than initial capacity, indicating that the addition of nutrient solution has obvious effect on the growth of Wolffia glo- bosa. However, the biomass of the experimental group was no longer increase after 2 weeks, indicating that there are some inhibitory factors in the incubators of the experimental group. The element detection results were as follows： the content pro- portions of N, P and K were 3.8：1：2.8, 11.5：1：17 and 5.2：1：6.8 in the experimental water, wild water and drying Wolffia globosa, respectively. The N, P, K in the water of experimental group was not exhausted, while the contents of Ca and Zn in three experimental incubators were below the limit of detection （ND）. And the contents of Mn in incubators No.l-No.3 were ND, 0.05 and 0.38 mg/L, respectively, presenting positive correlation with the biomass of Wolffia globosa. The inhibitory growth of Wolffia globosa is closely related with the absence of Ca, Mn and Zn in the nutrient solution. [Conclusion] The experimental results provided valuable parameters for the improvement on the formula of the original nutrient solution.

Forestry ecological footprint in China during 1973–2003

The ecological footprint （EF） model has received much attention as an assessment indicator for sustainable development in recent years. Firstly, the temporal changes of domestic timber production, imports and exports in China were analyzed from 1973 to 2003, the analysis results showed an apparent fluctuation in timber production during 1973-1995 but a decreasing trend during 1995-2002, an increasing trend in timber imports since 1995 especially after the implementation of the Natural Forest Protection Project （NFPP）, an decreasing trend year by year in timber exports since 1995. Secondly, this paper presented a time series analysis of actual forest area demand in the sustainable yield and production approach in China from 1973 to 2003, which includes both import and export forest area demand. The results showed the actual forest area demand simulated from the sustainable yield approach was slightly higher than that from the production approach during 1978-1988 and a little lower during 1989-2003; however, the actual forest area demands simulated by these two model approaches were larger than calculations that expressed in conventional forest EF. Meanwhile, the results indicated the forestry development in China during 1978-1988 was unsustainable due to overexploitation of forest stocking volumes, and China＇s forestry moved toward sustainable development since 1989 because forest resources are exploited at lower rates than they are regenerated. However, compared to forestry developed countries, the forestry development capacity in China is still lower. Finally, based on the model results we analyzed the relationships between forestry EF and the key policies, including trade policy, economic policy and forest conservation programs. In addition, several suggestions about reducing forestry EF and enhancing sustainable forestry development in China are given.

Remanufacturing production planning considering quality cost and demand substitution

Aiming to minimize the total production costs in a single planning period, a nonlinear integer programming model for remanufacturing production plans is established considering the influence of different qualities of returns acting on production cost. Three different remanufacturing and discarding strategies are adopted to analyze the change rules of the total production costs. The results returns is greater than indicate that when the number of remanufacturing returns of high the demand, preferentially quality and discarding those of low quality can bring better economic benefits due to manufacturing cost reduction. However, when the number of returns is smaller than the demand, there is no need to consider grading of returns, whereas new demand of remanufacturing. parts are required to satisfy the

Impact analysis of supplier relationship on supply chain resilience using biological cellular resilience theory

A supply chain resilience model is established based on the biological cellular resilience theory to analyze the impact of the supplier relationship on supply chain resilience. A scenario where the market demand is changed suddenly by some undesired events is considered. The results reveal that enhancing collaboration with a more resilient supplier can significantly improve supply chain resilience and reduce supply chain losses. It is also found that enhancing the supplier relationship can significantly benefit supply chain resilience if the collaborative intensity is relatively low, and it has less effect if supply chain members have already collaborated closely. Thus, enhancing the supplier relationship to a limited intensity is a relatively effective and economic method to strengthen supply chain resilience.

PERSPECTIVE OF COAL DEVELOPMENT OF CHINA IN THE EARLY 2000'S

According to the Researches on Coal Development Strategies in China (1991 ~ 2020),the production scale of coal in China will increase to 2100 Mt in the year 2020 and the district layout of coal development and production will be diverted from the east to the central-west step by step. In addit1on, the multi-ply runnning struc ture-mines of the nation,the local and the village and town combined with produc tion scales of the large, the middle,and the small-will be kept. However,the tech nique of mining will be improved greatly.

The eco-nutrition requirements for dietary protein and its rhomb characteristics in juvenile turbot (Scophthalmus maximus L.)

We evaluated the dietary protein requirements of juvenile turbot (Scophthalmus maximus L.) and their effects on aquatic quality. Five experimental diets were formulated containing 450, 480, 500, 520, and 540 g/kg. Each diet was randomly assigned to triplicate groups of juvenile turbot (mean initial body weight 34.5 ± 5.5 g) for 88 d. Both the weight gain ratio and feed efficiency increased with increasing dietary protein up to 500 g/kg, but no further improvement was detected when dietary protein levels were >500 g/kg. Protein intake and digestion increased with protein levels, while fecal nitrogen and nitrogen content in seawater increased only when dietary protein exceeded 500 g/kg. Protein digestibility was highest at intermediate dietary protein levels. Chemical oxygen demand, nitrite-nitrogen (NO2--N) and phosphatic-phosphor (PO43--P) levels increased in the rearing water as dietary protein levels increased. The optimum eco-nutrition level of dietary protein for juvenile turbot was 500 g/kg under the current experimental conditions. The diets containing 540 and 500 g/kg protein had similar growth rates and feed conversion ratios, but levels of ammonia (NH4+) and nitrogen were considerably higher in the water and feces, respectively, at the higher level of dietary protein. The difference in the pattern of change between body weight gain and ammonia concentration in water with increasing dietary protein is described by rhomb characteristics.

Influences of Oyster Shell Soil Conditioner on Soil and Plant Rhizospheric Microorganisms

Oyster shell soil conditioner had significant influence on soil and rhizospheric microorganisms in their biomass,respiratory intensity and nutritional requirement. It could stimulate growth of soil and rhizospheric microorganisms, especially nitrogen-fixers, and intensify soil respiration in proportion to the dose and fertilizing time of the conditioner, leading to the increase in the number of nitrogen fixing bacteria and the decrease in the number of bacteria with special nutrition demands.

A Study on Feelings of Worriment Due to Middle-Sized Robot in Living Space

Recently, the demand of services for architectural space is more increasing due to the diversification and complication of people＇s needs. In this research, it is assumed that the robot will support people＇s various needs and people＇s lives in the near future. In this study, the authors investigated the relationship between a robot and a person in quasi space close to actual life space. The authors carried out an experiment to clarify the feelings of worriment due to a robot in the living room in the case of Japanese males. This research aims to establish architecture techniques for robots and humans living together. In this experiment, the robot approached a male sitting on a sofa in quasi space. At different distances between the robot and the male, the subject evaluated his feelings of worriment from ＂no worriment＂ to ＂worriment＂ in five steps from one to five. The robot used in this experiment is middle-sized （380 mm （L） × 380 mm （W） × 350 mm （H））. In this experiment, it is considered that the robot asks for help outside when an emergency occurs. In this experiment, the authors had three situations for the subject： watching television, reading a magazine and just sitting.

Quality of effluents from Hattar Industrial Estate

Of 6634 registered industries in Pakistan, 1228 are considered to be highly polluting. The major industries include textile, pharmaceutical, chemicals (organic and inorganic), food industries, ceramics, steel, oil mills and leather tanning which spread all over four provinces, with the larger number located in Sindh and Punjab, with smaller number in North Western Frontier Province (NWFP) and Baluchistan. Hattar Industrial Estate extending over 700 acres located in Haripur district of NWFP is a new industrial estate, which has been developed with proper planning for management of industrial effluents. The major industries located in Hattar are ghee industry, chemical (sulfuric acid, synthetic fiber) industry, textile industry and pharmaceuticals industry. These industries, although developed with proper planning are discharging their effluents in the nearby natural drains and ulti- mately collected in a big drain near Wah. The farmers in the vicinity are using these effluents for growing vegetables and cereal crops due to shortage of water. In view of this discussion, there is a dire need to determine if these effluents are hazardous for soil and plant growth. So, effluents from different industries, sewage and normal tap water samples were collected and analysed for pH, electrical conductivity (EC), total soluble salts (TSS), biological oxygen demand (BOD), chemical oxygen demand (COD), total nitrogen, cations and anions and heavy metals. The effluents of ghee and textile industries are highly alkaline. EC and TSS loads of ghee and textile industries are also above the National Environmental Quality Standards (NEQS), Pakistan. All the effluents had residual sodium carbonates (RSCs), carbonates and bicarbonates in amounts that cannot be used for irrigation. Total toxic metals load in all the effluents is also above the limit i.e. 2.0 mg/L. Copper in effluents of textile and sewage, manganese in ghee industry effluents and iron contents in all the effluents were higher than NEQS. BOD and COD values of all the industries are also above the NEQS. On the whole, these effluents cannot be used for irrigation without proper treatment otherwise that may cause toxicity to soil, plants and animals as well add to the problems of salinity and sododicity. Similarly, these effluents cannot be used for fish farming.

Lived experiences with unmet supportive care needs in pediatric cancer:Perspective of Chinese children and their parents

Objective:Unmet supportive care needs(SCNs)impact pediatric cancer patients and their parents.This study aimed to explore the unmet SCNs from the perspective of Chinese children with cancer and their parents through lived experiences.Methods:The data of this study was collected using face-to-face semi-structured interviews.The participants were recruited from the oncology units of three children’s hospitals in China’s cities(Shanghai,Guangzhou,and Hefei)from October 2020 to December 2021.Data were analyzed using Colaizzi’s sevenstep phenomenological analysis method.Results:Eight pediatric cancer patients and twenty-four parents were enrolled in the study.Four main themes and eight subthemes(both children’s and parent’s perspectives)were generated:1)meeting the ongoing needs along the cancer trajectory(can you tell me what comes next;our needs are growing);2)communicating with a family focus(they only talk to my parents;let each family member have a voice);3)providing care beyond the treatment(I am bigger than my body[the children’s needs for emotional consolidation and information about their prognosis];there are things beyond treatment);4)getting support from the community(I am not a monster[the children were unhappy about being treated differently];we want to connect with the resources near us).Conclusion:This study revealed multiple unmet SCNs from the perspective of Chinese children with cancer and their parents.The findings call for comprehensive and in-depth supportive care beyond treatment,integration of the family member voice in pediatric cancer care,and a coordinated pediatric cancer support mechanism in the Chinese healthcare system.
