METHODS FOR ESTIMATING A DISINFESTATION RATE OF DISINFESTATION EQUIPMENT
Methods for accurately and efficiently estimating a disinfestation rate of disinfestation equipment and making adjustments based on the estimated disinfestation rate to achieve a desired disinfestation rate are provided. In one example, a disinfestation rate may be based on a number of infested products in an untreated sample out of a total number of products in the untreated sample and based on a number of infested products in a treated sample out of a total number of products in the treated sample. The estimated disinfestation rate may displayed, for example, and parameters of the disinfestation equipment may be adjusted in response to the estimated disinfestation rate
1 . A method, comprising:
estimating a disinfestation rate based on a number of infested products in an untreated sample out of a total number of products in the untreated sample and based on a number of infested products in a treated sample out of a total number of products in the treated sample; and
displaying the estimated disinfestation rate.
2 . The method of claim 1 , wherein the products in the untreated sample have not been treated by disinfestation equipment, and wherein the products in the treated sample have been treated by the disinfestation equipment.
3 . The method of claim 1 , wherein the infested products are products that contain any live infestation.
4 . The method of claim 1 , wherein estimating the disinfestation rate includes estimating a survival rate based on the number of infested products out of the total number of products for both the untreated sample and the treated sample, and updating an aggregated likelihood function of the survival rate with the estimated survival rate.
5 . The method of claim 1 , further comprising displaying calculations used to estimate the disinfestation rate.
6 . The method of claim 4 , wherein the calculations used to estimate the disinfestation rate include calculations to determine an ongoing estimate of a survival rate.
7 . A method, comprising:
receiving infestation information;
estimating a disinfestation rate based on the received infestation information; and
adjusting parameters of disinfestation equipment in response to the estimated disinfestation rate.
8 . The method of claim 7 , wherein estimating the disinfestation rate includes comparing an ongoing estimate of a survival rate with a pass-fail curve.
9 . The method of claim 8 , wherein the ongoing estimate of the survival rate is based upon the received infestation information and historical infestation information.
10 . The method of claim 7 , wherein the infestation information received is infestation information for a sample of treated products and infestation information for a sample of untreated products.
11 . The method of claim 7 , wherein adjusting the parameters of the disinfestation equipment includes adjusting a processing time for a treatment performed by the disinfestation equipment.
12 . The method of claim 7 , wherein adjusting the parameters of the disinfestation equipment includes adjusting a temperature threshold.
13 . The method of claim 7 , wherein the parameters of the disinfestation equipment are adjusted in response to the estimated disinfestation rate being less than a desired disinfestation rate.
14 . A method, comprising:
treating a portion of food products out of a total number of food products with disinfestation equipment, where a remainder of the total number of food products are untreated by the disinfestation equipment;
determining infestation information for the food products treated with the disinfestation equipment;
determining infestation information for the food products untreated by the disinfestation equipment; and
estimating a disinfestation rate of the disinfestation equipment based on the determined infestation information for the food products untreated by the disinfestation equipment and the food products treated with the disinfestation equipment.
15 . The method of claim 14 , further comprising displaying the estimated disinfestation rate of the disinfestation equipment.
16 . The method of claim 14 , further comprising adjusting operating parameters of the disinfestation equipment responsive to the estimated disinfestation rate of the disinfestation equipment.
17 . The method of claim 16 , wherein the operating parameters of the disinfestation equipment are adjusted responsive to the estimated disinfestation rate of the disinfestation equipment being less than a desired disinfestation rate.
18 . The method of claim 14 , wherein estimating the disinfestation rate includes estimating a survival rate based on the infestation information determined for the untreated food products and the infestation information determined for the treated food products.
19 . The method of claim 18 , wherein estimating the disinfestation rate further includes updating an aggregated likelihood function of the survival rate with the estimated survival rate.
20 . The method of claim 19 , wherein estimating the disinfestation rate further includes estimating the disinfestation rate based on a maximum likelihood estimate from the updated aggregated likelihood function of the survival rate.
